Charges allowing terms

i. Overview

To each charge spectrum `x : ChargeSpectrum 𝓩` we say it allows the potential term `T : PotentialTerm`, if one of the charges associated with that potential term is zero.

What this means, is that there is a choice of charges from the charge spectrum `x` that can be assigned to the fields in the potential term `T` such that the total charge is zero, and therefore that the term is present in the potential. The presence of absence of certain terms is of phenomenological importance.

This concept is captured by the proposition `AllowsTerm`.

In addition to this, for each potential term `T`, we define a function `allowsTermForm` which takes three elements of `𝓩`, `a`, `b`, and `c` and returns a charge spectrum which allows the term `T`. We will show in `allowsTerm_iff_subset_allowsTermForm` that any charge spectrum that allows a term `T` has a subset which can be expressed as `allowsTermForm a b c T` for some `a`, `b`, and `c`.

We also define the propositions `AllowsTermQ5 x q5 T` and `AllowsTermQ10 x q10 T` which correspond to the condition that adding a charge `q5` to the `Q5` charges of the charge spectrum `x`, or adding a charge `q10` to the `Q10` charges of the charge spectrum `x`, leads to a zero charge in the charges of potential term `T`.

A. Charge spectrums allowing potential terms

We first define the proposition `AllowsTerm`, which for a charge spectrum `x : ChargeSpectrum 𝓩` and a potential term `T : PotentialTerm`, is true if the zero charge is in the set of charges associated with that potential term.

That is, if there is some choice of representations present in the theory which will allow that potential term via symmetry.

A.1. Decidability of `AllowsTerm`

We define the decidability of `AllowsTerm` through `ofPotentialTerm'` rather than `ofPotentialTerm` due to the speed of the former compared to the latter.

A.2. Monotonicity of `AllowsTerm`

The proposition `AllowsTerm` is monotone in its charge spectrum argument. That is if a charge spectrum `y` is a subset of a charge spectrum `x`, and `y` allows a potential term `T`, then `x` also allows that potential term `T`.

B. Forms of charges which allow potential terms

We now define the function `allowsTermForm` which for each potential term `T` and three charges `a`, `b`, and `c` returns a charge spectrum which allows the term `T`.

These charges are in a minimal form, in the sense that any charge spectrum allowing `T` has a subset of this form.

B.1. `allowsTermForm` allows the potential term

Any charge spectrum of the form `allowsTermForm a b c T` allows the potential term `T`.

B.2. Subset relations for `allowsTermForm`

For any potential term `T` except for `W¹ᵢⱼₖₗ 10ⁱ 10ʲ 10ᵏ 5̄Mˡ` or `W²ᵢⱼₖ 10ⁱ 10ʲ 10ᵏ 5̄Hd`, a charge spectrum `allowsTermForm a b c T` is a subset of another charge spectrum `allowsTermForm a' b' c' T` if they are equal.

The reason this does not work for `W1` an `W2` is due to the presence of three charges in the 10d representation.

B.3. Card of `allowsTermForm`

The cardinality of the charge spectrum `allowsTermForm a b c T` is always less than or equal to the degree of the potential term `T`.

B.4. If `AllowsTerm` then subset equal to `allowsTermForm a b c T`

We now show one of the more important properties of `allowsTermForm`. Namely that if a charge spectrum `x` allows a potential term `T`, then there exists charges `a`, `b`, and `c` such that `allowsTermForm a b c T ⊆ x`.

The proof of this result is rather long, relying on case-by-case analysis of each of the potential terms of interest.

B.5. `AllowsTerm` if and only if subset equal to `allowsTermForm a b c T`

We now lift the previous result to show that a charge spectrum `x` allows a potential term `T` if and only if there exists charges `a`, `b`, and `c` such that `allowsTermForm a b c T ⊆ x`.

Given what has already been shown, this result is now trivial.

B.6. Cardinality of subset allowing potential term

We show that if a charge spectrum `x` allows a potential term `T`, then there exists a subset of `x` which allows `T` and whose cardinality is less than or equal to the degree of `T`.

This follows from the fact that `allowsTermForm a b c T` always has cardinality less than or equal to the degree of `T`.

C. Allowing a potential term by insertion of a `Q5` charge

We now study what happens when we add a charge `q5` to the `Q5` charges of a charge spectrum `x`. We define the proposition `AllowsTermQ5 x q5 T` which is true if adding the charge `q5` to the `Q5` charges of `x` allows the potential term `T` due to the addition of that charge.

We prove a number of properties of this proposition, including its relation to `AllowsTerm` and its decidability.

C.1. Decidability of `AllowsTermQ5`

We show that if the type `𝓩` has decidable equality, then the proposition `AllowsTermQ5 x q5 T` is decidable for any charge spectrum `x`, charge `q5`, and potential term `T`.

C.2. AllowsTermQ5 or AllowsTerm from AllowsTerm with inserted of `Q5` charge

We show that if a charge spectrum `x` with an inserted charge `q5` allows a potential term `T`, then either the charge spectrum `x` allows that potential term `T` *due to* the addition of that charge, or the charge spectrum `x` already allows that potential term `T`.

C.3. AllowsTerm with inserted of `Q5` charge from AllowsTermQ5

We show that if a charge spectrum `x` allows a potential term `T` *due to* the addition of a charge `q5`, then the charge spectrum `x` with that charge inserted allows that potential term `T`.

C.4. AllowsTerm with inserted of `Q5` charge iff AllowsTermQ5 or AllowsTerm

We show that the charge spectrum `x` with that charge inserted allows that potential term `T` if and only if either the charge spectrum `x` allows that potential term `T` *due to* the addition of that charge, or the charge spectrum `x` already allows that potential term `T`.

D. Allowing a potential term by insertion of a `Q10` charge

We now replicate the previous section, but for the insertion of a `Q10` charge, rather than a `Q5` charge.

We study what happens when we add a charge `q10` to the `Q10` charges of a charge spectrum `x`. We define the proposition `AllowsTermQ10 x q10 T` which is true if adding the charge `q10` to the `Q10` charges of `x` allows the potential term `T` due to the addition of that charge.

We prove a number of properties of this proposition, including its relation to `AllowsTerm` and its decidability.

D.1. Decidability of `AllowsTermQ5`

We show that if the type `𝓩` has decidable equality, then the proposition `AllowsTermQ10 x q10 T` is decidable for any charge spectrum `x`, charge `q10`, and potential term `T`.

D.2. AllowsTermQ10 or AllowsTerm from AllowsTerm with inserted of `Q10` charge

We show that if a charge spectrum `x` with an inserted charge `q10` allows a potential term `T`, then either the charge spectrum `x` allows that potential term `T` *due to* the addition of that charge, or the charge spectrum `x` already allows that potential term `T`.

D.3. AllowsTerm with inserted of `Q10` charge from AllowsTermQ5

We show that if a charge spectrum `x` allows a potential term `T` *due to* the addition of a charge `q10`, then the charge spectrum `x` with that charge inserted allows that potential term `T`.

D.4. AllowsTerm with inserted of `Q10` charge iff AllowsTermQ10 or AllowsTerm

We show that the charge spectrum `x` with that charge inserted allows that potential term `T` if and only if either the charge spectrum `x` allows that potential term `T` *due to* the addition of that charge, or the charge spectrum `x` already allows that potential term `T`.

definition

Charge spectrum xx allows potential term TT

Let Z\mathcal{Z} be an abelian group of charges and xx be a charge spectrum that assigns a multiset of charges to various field labels in an SU(5)SU(5) supersymmetric theory. A potential term TT is said to be **allowed** by the charge spectrum xx if the additive identity 0Z0 \in \mathcal{Z} is an element of the multiset of all possible total charges associated with TT under the spectrum xx. More explicitly, if TT is an interaction term composed of fields F1,F2,,FnF_1, F_2, \dots, F_n, and xx assigns the multiset of charges SiZS_i \subset \mathcal{Z} to the field FiF_i, then xx allows TT if there exists a selection of charges ziSiz_i \in S_i such that their sum vanishes: i=1nzi=0 \sum_{i=1}^n z_i = 0 This condition signifies that there is a combination of field charges present in the spectrum that makes the potential term TT gauge-invariant (invariant under the symmetry group associated with Z\mathcal{Z}).

theorem

x.AllowsTerm T    0x.ofPotentialTermTx.\text{AllowsTerm } T \iff 0 \in x.\text{ofPotentialTerm}' T

Let xx be a charge spectrum and TT be a potential term in an SU(5)SU(5) supersymmetric theory with charges in an abelian group Z\mathcal{Z}. The spectrum xx allows the potential term TT if and only if the additive identity 0Z0 \in \mathcal{Z} is an element of the multiset of possible total charges x.ofPotentialTermTx.\text{ofPotentialTerm}' T.

instance

Decidability of x.AllowsTerm Tx.\text{AllowsTerm } T

For a charge spectrum xx and a potential term TT within an SU(5)SU(5) theory, the property that xx allows TT (denoted x.AllowsTerm Tx.\text{AllowsTerm } T) is decidable, provided that equality is decidable in the underlying charge group Z\mathcal{Z}. This means that it can be computationally determined whether there exists a selection of charges from xx assigned to the fields in TT such that their sum equals the additive identity 0Z0 \in \mathcal{Z}.

theorem

Monotonicity of `AllowsTerm` under spectrum inclusion yxy \subseteq x

Let Z\mathcal{Z} be an abelian group of charges. For any potential term TT and any two SU(5)SU(5) charge spectra x,yChargeSpectrum Zx, y \in \text{ChargeSpectrum } \mathcal{Z}, if yy is a subset of xx (denoted yxy \subseteq x) and yy allows the potential term TT, then xx also allows the potential term TT.

definition

Minimal charge spectrum form for potential term TT given a,b,cZa, b, c \in \mathcal{Z}

For a potential term TT and three charges a,b,ca, b, c in the charge group Z\mathcal{Z}, the function `allowsTermForm` constructs a `ChargeSpectrum` representing the minimal set of charges assigned to the fields Hu,Hd,M,H_u, H_d, M, and 1010 required to allow that term. This spectrum is defined such that at least one combination of these charges satisfies the gauge invariance condition (the total charge sums to zero) for the specific interaction TT. The charge assignments for each potential term TT are as follows: - For T=μT = \mu (Higgs mass term μHu5ˉH\mu H_u \bar{5}_H): HdH_d has charge {a}\{a\} and HuH_u has charge {a}\{a\}. - For T=βT = \beta (matter-Higgs mixing β5ˉMHu\beta \bar{5}_M H_u): HuH_u has charge {a}\{a\} and MM has charge {a}\{a\}. - For T=ΛT = \Lambda (trilinear matter interaction λ5ˉM5ˉM10\lambda \bar{5}_M \bar{5}_M 10): MM has charges {a,b}\{a, b\} and 1010 has charge {ab}\{-a-b\}. - For T=W1T = W^1 (1035ˉM10^3 \bar{5}_M): MM has charge {abc}\{-a-b-c\} and 1010 has charges {a,b,c}\{a, b, c\}. - For T=W2T = W^2 (1035ˉH10^3 \bar{5}_H): HdH_d has charge {abc}\{-a-b-c\} and 1010 has charges {a,b,c}\{a, b, c\}. - For T=W3T = W^3 (5ˉM2Hu2\bar{5}_M^2 H_u^2): HuH_u has charge {a}\{-a\} and MM has charges {b,b2a}\{b, -b-2a\}. - For T=W4T = W^4 (5ˉM5ˉHHu2\bar{5}_M \bar{5}_H H_u^2): HdH_d has charge {c2b}\{-c-2b\}, HuH_u has charge {b}\{-b\}, and MM has charge {c}\{c\}. - For T=K1T = K^1 (1025M10^2 5_M): MM has charge {a}\{-a\} and 1010 has charges {b,ab}\{b, -a-b\}. - For T=K2T = K^2 (5ˉHu5ˉHd10\bar{5}_{H_u} \bar{5}_{H_d} 10): HdH_d has charge {a}\{a\}, HuH_u has charge {b}\{b\}, and 1010 has charge {ab}\{-a-b\}. - For T=topYukawaT = \text{topYukawa} (1025Hu10^2 5_{H_u}): HuH_u has charge {a}\{-a\} and 1010 has charges {b,ab}\{b, -a-b\}. - For T=bottomYukawaT = \text{bottomYukawa} (105ˉM5ˉH10 \bar{5}_M \bar{5}_H): HdH_d has charge {a}\{a\}, MM has charge {b}\{b\}, and 1010 has charge {ab}\{-a-b\}.

theorem

allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) allows term TT

Let Z\mathcal{Z} be an abelian group of charges and TT be a potential term in an SU(5)SU(5) supersymmetric theory. For any charges a,b,cZa, b, c \in \mathcal{Z}, the charge spectrum constructed by allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) allows the potential term TT. This means there exists a selection of charges from the spectrum for the fields constituting TT such that their sum is the additive identity 0Z0 \in \mathcal{Z}.

theorem

x=allowsTermForm(a,b,c,T)x = \text{allowsTermForm}(a, b, c, T) implies xx allows TT

Let Z\mathcal{Z} be an abelian group of charges. For any potential term TT and charge spectrum xx, if there exist charges a,b,cZa, b, c \in \mathcal{Z} such that x=allowsTermForm(a,b,c,T)x = \text{allowsTermForm}(a, b, c, T), then the charge spectrum xx allows the potential term TT. This means there exists a selection of charges from the spectrum xx for the fields constituting TT such that their sum is the additive identity 0Z0 \in \mathcal{Z}.

theorem

allowsTermForm(a,b,c,T)allowsTermForm(a,b,c,T)    allowsTermForm(a,b,c,T)=allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) \subseteq \text{allowsTermForm}(a', b', c', T) \implies \text{allowsTermForm}(a, b, c, T) = \text{allowsTermForm}(a', b', c', T) for TW1,W2T \neq W^1, W^2

Let Z\mathcal{Z} be an abelian group of charges. For any charges a,b,c,a,b,cZa, b, c, a', b', c' \in \mathcal{Z} and any potential term TT of the SU(5)SU(5) SUSY GUT, excluding the dimension-5 operators W1W^1 (1035ˉM10^3 \bar{5}_M) and W2W^2 (1035ˉHd10^3 \bar{5}_{H_d}), if the minimal charge spectrum allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) is a subset of allowsTermForm(a,b,c,T)\text{allowsTermForm}(a', b', c', T) (denoted by the component-wise subset relation \subseteq), then the two charge spectra are equal: allowsTermForm(a,b,c,T)=allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) = \text{allowsTermForm}(a', b', c', T).

theorem

card(allowsTermForm(a,b,c,T))deg(T)\text{card}(\text{allowsTermForm}(a, b, c, T)) \leq \text{deg}(T)

For any charges a,b,ca, b, c in the charge group Z\mathcal{Z} and any potential term TT in an SU(5)SU(5) supersymmetric grand unified theory, the cardinality of the minimal charge spectrum constructed by allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) is less than or equal to the degree of the potential term TT. Mathematically, this is expressed as: card(allowsTermForm(a,b,c,T))deg(T) \text{card}(\text{allowsTermForm}(a, b, c, T)) \leq \text{deg}(T) where card(x)\text{card}(x) denotes the total number of charges in the spectrum xx, and deg(T)\text{deg}(T) is the number of field labels that constitute the interaction term TT.

theorem

If xx allows TT, then allowsTermForm(a,b,c,T)x\text{allowsTermForm}(a, b, c, T) \subseteq x for some a,b,cZa, b, c \in \mathcal{Z}

Let Z\mathcal{Z} be an abelian group of charges. For any potential term TT and any SU(5)SU(5) charge spectrum xx over Z\mathcal{Z}, if xx allows the potential term TT (meaning there exists a selection of charges for the fields in TT from the spectrum xx that sums to zero), then there exist charges a,b,cZa, b, c \in \mathcal{Z} such that the minimal charge spectrum allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) is a subset of xx and allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) itself allows the potential term TT.

theorem

x allows T    a,b,c,allowsTermForm(a,b,c,T)xx \text{ allows } T \iff \exists a, b, c, \text{allowsTermForm}(a, b, c, T) \subseteq x

Let Z\mathcal{Z} be an abelian group of charges. For any potential term TT in an SU(5)SU(5) supersymmetric theory and any charge spectrum xx over Z\mathcal{Z}, the spectrum xx allows the term TT if and only if there exist charges a,b,cZa, b, c \in \mathcal{Z} such that the minimal charge spectrum allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) is a subset of xx.

theorem

If xx allows TT, there exists yxy \subseteq x with card(y)deg(T)\text{card}(y) \le \text{deg}(T) that allows TT

Let Z\mathcal{Z} be an abelian group of charges. Suppose an SU(5)SU(5) charge spectrum xx allows a potential term TT. Then there exists a subset charge spectrum yxy \subseteq x such that yy also allows TT and the cardinality of yy is less than or equal to the degree of the term TT: card(y)deg(T) \text{card}(y) \le \text{deg}(T) where card(y)\text{card}(y) is the total number of charges in the spectrum yy, and deg(T)\text{deg}(T) is the number of fields constituting the interaction term TT.

definition

Potential term TT is allowed by the addition of charge q5q_5 to xx

Given a charge spectrum xx with Higgs charges qHd,qHuZ{}q_{H_d}, q_{H_u} \in \mathcal{Z} \cup \{\bot\} and sets of matter charges Q5,Q10ZQ_5, Q_{10} \subset \mathcal{Z}, the proposition `AllowsTermQ5 x q5 T` defines whether adding a charge q5Zq_5 \in \mathcal{Z} to the 5\mathbf{\overline{5}} representation allows the potential term TT due to the inclusion of q5q_5. The conditions for each term TT are: - For μ\mu: Always false. - For βi\beta_i: qHuq_{H_u} \neq \bot and q5=qHuq_5 = q_{H_u}. - For λijk\lambda_{ijk}: There exist q1Q5{q5}q_1 \in Q_5 \cup \{q_5\} and q2Q10q_2 \in Q_{10} such that q1+q5+q2=0q_1 + q_5 + q_2 = 0. - For Wi4W^4_i: qHdq_{H_d} \neq \bot, qHuq_{H_u} \neq \bot, and q5+qHd2qHu=0q_5 + q_{H_d} - 2q_{H_u} = 0. - For Kijk1K^1_{ijk}: There exist q1,q2Q10q_1, q_2 \in Q_{10} such that q5+q1+q2=0-q_5 + q_1 + q_2 = 0. - For Wijkl1W^1_{ijkl}: There exist q1,q2,q3Q10q_1, q_2, q_3 \in Q_{10} such that q5+q1+q2+q3=0q_5 + q_1 + q_2 + q_3 = 0. - For Wijk2W^2_{ijk}: Always false. - For the bottom Yukawa term: qHdq_{H_d} \neq \bot and there exists yQ10y \in Q_{10} such that y+q5+qHd=0y + q_5 + q_{H_d} = 0. - For the top Yukawa term: Always false. - For Ki2K^2_i: Always false. - For Wij3W^3_{ij}: qHuq_{H_u} \neq \bot and there exists yQ5{q5}y \in Q_5 \cup \{q_5\} such that y+q52qHu=0y + q_5 - 2q_{H_u} = 0.

instance

Decidability of whether adding charge q5q_5 allows potential term TT

Given a charge group Z\mathcal{Z} with decidable equality, for any charge spectrum xx, charge q5Zq_5 \in \mathcal{Z}, and potential term TT, it is decidable whether the term TT is allowed in the theory's potential due to the addition of q5q_5 to the 5\mathbf{\overline{5}} representation matter charges. This decidability is established by evaluating the specific charge constraints associated with the term TT (such as the Higgs mass term μ\mu, Yukawa couplings, or dimension-5 operators) against the charges present in xx and the additional charge q5q_5.

theorem

Allowing TT with inserted q5q_5 implies `AllowsTerm` or `AllowsTermQ5`

Let Z\mathcal{Z} be an abelian group of charges. Consider an SU(5)SU(5) SUSY GUT charge spectrum xx characterized by Higgs charges qHd,qHuZ{}q_{H_d}, q_{H_u} \in \mathcal{Z} \cup \{\bot\} and finite sets of matter charges Q5,Q10ZQ_5, Q_{10} \subset \mathcal{Z}. For any potential term TT and any additional charge q5Zq_5 \in \mathcal{Z}, if TT is allowed by the charge spectrum formed by inserting q5q_5 into the set Q5Q_5 (i.e., the spectrum qHd,qHu,Q5{q5},Q10\langle q_{H_d}, q_{H_u}, Q_5 \cup \{q_5\}, Q_{10} \rangle), then either the original spectrum qHd,qHu,Q5,Q10\langle q_{H_d}, q_{H_u}, Q_5, Q_{10} \rangle already allows TT, or TT is allowed specifically due to the inclusion of q5q_5 as defined by the proposition `AllowsTermQ5`.

theorem

`AllowsTermQ5` implies `AllowsTerm` with inserted charge q5q_5

Consider a charge spectrum with Higgs charges qHd,qHuZ{}q_{H_d}, q_{H_u} \in \mathcal{Z} \cup \{\bot\} and sets of matter charges Q5,Q10ZQ_5, Q_{10} \subseteq \mathcal{Z}. For any potential term TT and charge q5Zq_5 \in \mathcal{Z}, if TT is allowed due to the addition of q5q_5 to the 5\mathbf{\overline{5}} representation (i.e., `AllowsTermQ5` holds for the spectrum qHd,qHu,Q5,Q10\langle q_{H_d}, q_{H_u}, Q_5, Q_{10} \rangle and charge q5q_5), then the charge spectrum obtained by inserting q5q_5 into Q5Q_5 allows the potential term TT.

theorem

Allowance of TT with inserted q5q_5     \iff `AllowsTerm` \lor `AllowsTermQ5`

Let Z\mathcal{Z} be an abelian group of charges. For any SU(5)SU(5) charge spectrum consisting of Higgs charges qHd,qHuZ{}q_{H_d}, q_{H_u} \in \mathcal{Z} \cup \{\bot\} and finite sets of matter charges Q5,Q10ZQ_5, Q_{10} \subset \mathcal{Z}, and for any potential term TT and additional charge q5Zq_5 \in \mathcal{Z}, the potential term TT is allowed by the augmented spectrum qHd,qHu,Q5{q5},Q10\langle q_{H_d}, q_{H_u}, Q_5 \cup \{q_5\}, Q_{10} \rangle if and only if TT is allowed specifically due to the addition of q5q_5 to the 5\mathbf{\overline{5}} representation (denoted by `AllowsTermQ5`) or TT is already allowed by the original spectrum qHd,qHu,Q5,Q10\langle q_{H_d}, q_{H_u}, Q_5, Q_{10} \rangle.

definition

Adding charge q10q_{10} to the spectrum xx allows the potential term TT

Given a charge spectrum xx consisting of Higgs charges qHdq_{H_d} and qHuq_{H_u}, a set of charges for fields in the 5\mathbf{\overline{5}} representation Q5Q_5, and a set of charges for fields in the 10\mathbf{10} representation Q10Q_{10}, the proposition `AllowsTermQ10 x q10 T` is true if the potential term TT is allowed by adding a specific charge q10q_{10} to the 1010-representation sector. The conditions for each potential term TT are as follows: - Λijk\Lambda_{ijk} (trilinear matter interaction λijk(5ˉMi)(5ˉMj)(10k)\lambda_{ijk} (\bar{5}M^i)(\bar{5}M^j)(10^k)): q5,q5Q5\exists q_5, q_5' \in Q_5 such that q5+q5+q10=0q_5 + q_5' + q_{10} = 0. - Kijk1K^1_{ijk} (Kähler term 10i10j5Mk10^i 10^j 5M^k): q5Q5\exists q_5 \in Q_5 and q10Q10{q10}q_{10}' \in Q_{10} \cup \{q_{10}\} such that q5+q10+q10=0-q_5 + q_{10}' + q_{10} = 0. - Wijkl1W^1_{ijkl} (dimension-5 operator 10i10j10k5ˉMl10^i 10^j 10^k \bar{5}M^l): q5Q5\exists q_5 \in Q_5 and q10,q10Q10{q10}q_{10}', q_{10}'' \in Q_{10} \cup \{q_{10}\} such that q5+q10+q10+q10=0q_5 + q_{10}' + q_{10}'' + q_{10} = 0. - Wijk2W^2_{ijk} (operator 10i10j10k5ˉHd10^i 10^j 10^k \bar{5}H_d): qHdq_{H_d} is present and q10,q10Q10{q10}\exists q_{10}', q_{10}'' \in Q_{10} \cup \{q_{10}\} such that qHd+q10+q10+q10=0q_{H_d} + q_{10}' + q_{10}'' + q_{10} = 0. - bottomYukawa\text{bottomYukawa}: qHdq_{H_d} is present and q5Q5\exists q_5 \in Q_5 such that q10+q5+qHd=0q_{10} + q_5 + q_{H_d} = 0. - topYukawa\text{topYukawa}: qHuq_{H_u} is present and q10Q10{q10}\exists q_{10}' \in Q_{10} \cup \{q_{10}\} such that q10+q10qHu=0q_{10} + q_{10}' - q_{H_u} = 0. - Ki2K^2_i (Kähler term 5ˉHu5ˉHd10i\bar{5}H_u \bar{5}H_d 10^i): qHdq_{H_d} and qHuq_{H_u} are both present and qHd+qHu+q10=0q_{H_d} + q_{H_u} + q_{10} = 0. - For T{μ,β,W4,W3}T \in \{\mu, \beta, W^4, W^3\}, the proposition is always false.

Decidability of `AllowsTermQ10 x q10 T`

Given a charge spectrum xx (consisting of Higgs charges qHd,qHuq_{H_d}, q_{H_u} and finite sets of representation charges Q5,Q10ZQ_5, Q_{10} \subset \mathcal{Z}), an SU(5)SU(5) potential term TT, and a specific charge q10Zq_{10} \in \mathcal{Z}, the proposition `AllowsTermQ10 x q10 T` is decidable, provided that equality in the charge group Z\mathcal{Z} is decidable. This proposition determines whether the interaction term TT can be formed with total charge zero by selecting charges from the spectrum xx and the newly provided charge q10q_{10} for the fields in the 10\mathbf{10} representation.

theorem

Allowedness of TT under Q10{q10}Q_{10} \cup \{q_{10}\} implies `AllowsTerm` or `AllowsTermQ10`

Let Z\mathcal{Z} be an abelian group of charges. Consider a potential term TT, a charge q10Zq_{10} \in \mathcal{Z}, and a charge spectrum xx consisting of Higgs charges qHd,qHuq_{H_d}, q_{H_u}, and sets of matter charges Q5Q_5 and Q10Q_{10}. If the potential term TT is allowed by the charge spectrum obtained by adding q10q_{10} to the 10\mathbf{10}-representation sector (i.e., using the set Q10{q10}Q_{10} \cup \{q_{10}\}), then either the original spectrum xx already allowed TT, or TT is allowed specifically due to the inclusion of the new charge q10q_{10} (the condition `AllowsTermQ10 x q10 T` holds).

theorem

`AllowsTermQ10` implies `AllowsTerm` for spectrum with q10q_{10} inserted

Let Z\mathcal{Z} be an abelian group of charges. Consider a charge spectrum x=(qHd,qHu,Q5,Q10)x = (q_{H_d}, q_{H_u}, Q_5, Q_{10}), where qHd,qHuq_{H_d}, q_{H_u} are optional Higgs charges and Q5,Q10ZQ_5, Q_{10} \subset \mathcal{Z} are finite sets of matter charges. For any potential term TT and any charge q10Zq_{10} \in \mathcal{Z}, if the proposition `AllowsTermQ10 x q10 T` holds (meaning TT is allowed specifically by using q10q_{10} as a charge for a field in the 10\mathbf{10} representation), then the potential term TT is allowed by the augmented charge spectrum (qHd,qHu,Q5,Q10{q10})(q_{H_d}, q_{H_u}, Q_5, Q_{10} \cup \{q_{10}\}).

theorem

`AllowsTerm` with inserted q10q_{10} iff `AllowsTermQ10` or `AllowsTerm`

Let Z\mathcal{Z} be an abelian group of charges. Consider a potential term TT, a charge q10Zq_{10} \in \mathcal{Z}, and an SU(5)SU(5) charge spectrum x=(qHd,qHu,Q5,Q10)x = (q_{H_d}, q_{H_u}, Q_5, Q_{10}). The augmented charge spectrum obtained by adding q10q_{10} to the 10\mathbf{10}-representation sector, (qHd,qHu,Q5,Q10{q10})(q_{H_d}, q_{H_u}, Q_5, Q_{10} \cup \{q_{10}\}), allows the term TT if and only if either the original spectrum xx already allowed TT or the term TT is allowed specifically due to the inclusion of q10q_{10} (i.e., the condition `AllowsTermQ10 x q10 T` holds).
