Mapping of an SU(5) charge spectrum under f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1

#map

Given an additive monoid homomorphism f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 and an SU(5) charge spectrum xx defined over Z\mathcal{Z}, the function returns a new charge spectrum over Z1\mathcal{Z}_1. The components of the new spectrum are obtained by mapping the Higgs charges qHdq_{H_d} and qHuq_{H_u} via ff, and taking the images of the finite sets of charges Q5Q_5 and Q10Q_{10} under ff.

theorem

map(f,)=\text{map}(f, \emptyset) = \emptyset

#map_empty

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids. For any additive monoid homomorphism f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1, the mapping of the empty SU(5)SU(5) charge spectrum \emptyset over Z\mathcal{Z} results in the empty SU(5)SU(5) charge spectrum over Z1\mathcal{Z}_1: map(f,)=\text{map}(f, \emptyset) = \emptyset

#map_id

Let xx be an SU(5) charge spectrum defined over an additive monoid Z\mathcal{Z}. Mapping the charge spectrum xx using the identity homomorphism idZ:ZZ\text{id}_{\mathcal{Z}}: \mathcal{Z} \to \mathcal{Z} returns the original spectrum xx: map(idZ,x)=x\text{map}(\text{id}_{\mathcal{Z}}, x) = x

#map_ofFieldLabel

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids. For any additive monoid homomorphism f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1, any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, and any field label FF, the set of charges associated with the field FF in the mapped spectrum map(f,x)\text{map}(f, x) is equal to the image under ff of the set of charges associated with FF in the original spectrum xx: ofFieldLabel(map(f,x),F)=f(ofFieldLabel(x,F))\text{ofFieldLabel}(\text{map}(f, x), F) = f(\text{ofFieldLabel}(x, F))

theorem

#map_subset

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids. For any additive monoid homomorphism f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 and any two SU(5)SU(5) charge spectra x,yx, y defined over Z\mathcal{Z}, if xyx \subseteq y, then their mapped spectra satisfy map(f,x)map(f,y)\text{map}(f, x) \subseteq \text{map}(f, y).

#mem_map_ofPotentialTerm_iff

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx over Z\mathcal{Z} and any potential term TT in the SU(5)SU(5) SUSY GUT, a charge value iZ1i \in \mathcal{Z}_1 is an element of the multiset of total charges for TT under the mapped spectrum map(f,x)\text{map}(f, x) if and only if ii is an element of the multiset obtained by mapping the multiset of total charges for TT under the original spectrum xx via ff.

#mem_map_ofPotentialTerm'_iff

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx over Z\mathcal{Z} and any potential term TT in the SU(5)SU(5) SUSY GUT, a charge value iZ1i \in \mathcal{Z}_1 is an element of the multiset of total charges ofPotentialTerm(map(f,x),T)\text{ofPotentialTerm}'(\text{map}(f, x), T) (the explicitly defined multiset of charges resulting from the combination of fields in TT) if and only if ii is an element of the multiset obtained by mapping the multiset of total charges for TT under the original spectrum xx via ff. That is, iofPotentialTerm(map(f,x),T)    i(ofPotentialTerm(x,T)).map(f)i \in \text{ofPotentialTerm}'(\text{map}(f, x), T) \iff i \in (\text{ofPotentialTerm}'(x, T)).\text{map}(f)

theorem

set(ofPotentialTerm(map(f,x),T))=f(set(ofPotentialTerm(x,T)))\text{set}(\text{ofPotentialTerm}'(\text{map}(f, x), T)) = f(\text{set}(\text{ofPotentialTerm}'(x, T)))

#map_ofPotentialTerm'_toFinset

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids with decidable equality, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx over Z\mathcal{Z} and any potential term TT in the SU(5)SU(5) SUSY GUT, the finite set of total charges for TT under the mapped spectrum map(f,x)\text{map}(f, x) is the image under ff of the finite set of total charges for TT under the original spectrum xx. That is, set(ofPotentialTerm(map(f,x),T))=f(set(ofPotentialTerm(x,T))) \text{set}(\text{ofPotentialTerm}'(\text{map}(f, x), T)) = f(\text{set}(\text{ofPotentialTerm}'(x, T))) where ofPotentialTerm\text{ofPotentialTerm}' denotes the multiset of charges resulting from the specific combination of matter and Higgs fields in the term TT, and set()\text{set}(\cdot) denotes the conversion of that multiset to a finite set.

theorem

The additive monoid homomorphism ff commutes with the potential term charge form `allowsTermForm`

#allowsTermForm_map

For any potential term TT of the SU(5)SU(5) SUSY GUT and any additive monoid homomorphism f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1, the mapping under ff of the charge interaction form allowsTermForm(a,b,c,T)\text{allowsTermForm}(a, b, c, T) for charges a,b,cZa, b, c \in \mathcal{Z} is equal to the charge interaction form evaluated with the mapped charges f(a),f(b)f(a), f(b), and f(c)f(c). That is, f(allowsTermForm(a,b,c,T))=allowsTermForm(f(a),f(b),f(c),T) f(\text{allowsTermForm}(a, b, c, T)) = \text{allowsTermForm}(f(a), f(b), f(c), T) where allowsTermForm\text{allowsTermForm} represents the specific combination of charges required for the potential term TT to be gauge-invariant or otherwise "allowed."

theorem

If xx allows term TT, then map(f,x)\text{map}(f, x) allows term TT

#map_allowsTerm

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z} and any potential term TT of the SU(5)SU(5) SUSY GUT (such as Yukawa interactions or Higgs mass terms), if xx allows the term TT, then the mapped charge spectrum f(x)f(x) also allows the term TT.

theorem

Mapping preserves the phenomenologically constrained property of charge spectra

#map_isPhenoConstrained

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, if xx is phenomenologically constrained, then the mapped charge spectrum x.map(f)x.\text{map}(f) is also phenomenologically constrained. A charge spectrum is considered phenomenologically constrained if it allows any of the potential terms μ,β,Λ,W1,W2,W4,K1\mu, \beta, \Lambda, W_1, W_2, W_4, K_1, or K2K_2 (associated with proton decay or R-parity violation in SU(5)SU(5) supersymmetry).

theorem

¬IsPhenoConstrained(map(f,x))    ¬IsPhenoConstrained(x)\neg \text{IsPhenoConstrained}(\text{map}(f, x)) \implies \neg \text{IsPhenoConstrained}(x)

#not_isPhenoConstrained_of_map

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, if the mapped charge spectrum map(f,x)\text{map}(f, x) is not phenomenologically constrained, then the original charge spectrum xx is also not phenomenologically constrained. A charge spectrum is considered phenomenologically constrained if it allows any of the potential terms (specifically μ,β,Λ,W1,W2,W4,K1\mu, \beta, \Lambda, W_1, W_2, W_4, K_1, or K2K_2) associated with proton decay or R-parity violation in SU(5)SU(5) supersymmetry.

theorem

x.map(f)x.\text{map}(f) is complete     x\iff x is complete

#map_isComplete_iff

Let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism between charge groups, and let xx be an SU(5)SU(5) charge spectrum defined over Z\mathcal{Z}. The mapped charge spectrum x.map(f)x.\text{map}(f) is complete if and only if the original charge spectrum xx is complete. Here, a spectrum is considered complete if the up-type and down-type Higgs charges are present and the sets of 5ˉ\bar{\mathbf{5}} and 10\mathbf{10} charges are non-empty.

theorem

The set of Yukawa charges of a mapped spectrum is the image of the original Yukawa charges under ff

#map_ofYukawaTerms_toFinset

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, the finite set of charges associated with the Yukawa terms of the mapped spectrum map(f,x)\text{map}(f, x) is equal to the image under ff of the finite set of charges associated with the Yukawa terms of the original spectrum xx. The Yukawa terms are defined as the sum of the charges from the top and bottom Yukawa couplings. That is, \[ (\text{map}(f, x)).\text{ofYukawaTerms}.\text{toFinset} = (\text{ofYukawaTerms}(x)).\text{toFinset}.\text{image}(f) \]

#mem_map_ofYukawaTerms_iff

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, a charge iZ1i \in \mathcal{Z}_1 is an element of the multiset of Yukawa charges of the mapped spectrum map(f,x)\text{map}(f, x) if and only if ii is an element of the multiset obtained by mapping the original multiset of Yukawa charges of xx via ff. That is, \[ i \in (\text{map}(f, x)).\text{ofYukawaTerms} \iff i \in (\text{ofYukawaTerms}(x)).\text{map}(f) \]

theorem

The Set of Sums of up to nn Yukawa Charges of a Mapped Spectrum is the Image of the Original Set

#map_ofYukawaTermsNSum_toFinset

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z} and any natural number nn, let S(x,n)S(x, n) denote the finite set of charges formed by summing up to nn charges from the multiset of Yukawa terms of xx. The theorem states that the set of such sums for the mapped spectrum map(f,x)\text{map}(f, x) is equal to the image under ff of the set of sums for the original spectrum xx: \[ \text{set}(\text{ofYukawaTermsNSum}(\text{map}(f, x), n)) = f(\text{set}(\text{ofYukawaTermsNSum}(x, n))) \] where set()\text{set}(\cdot) denotes the conversion of a multiset of charges to a finite set.

#mem_map_ofYukawaTermsNSum_iff

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, a natural number nn, and a charge iZ1i \in \mathcal{Z}_1, ii is an element of the multiset of charges formed by summing up to nn Yukawa charges of the mapped spectrum map(f,x)\text{map}(f, x) if and only if ii is an element of the multiset obtained by mapping the corresponding sums of the original spectrum xx via ff. That is, \[ i \in (\text{map}(f, x)).\text{ofYukawaTermsNSum}(n) \iff i \in (\text{ofYukawaTermsNSum}(x, n)).\text{map}(f) \]

theorem

set(P(map(f,x)))=f(set(P(x)))\text{set}(P(\text{map}(f, x))) = f(\text{set}(P(x))) for Pheno-Constraining Charges

#map_phenoConstrainingChargesSP_toFinset

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z}, the finite set of charges associated with the phenomenologically constraining superpotential terms of the mapped spectrum map(f,x)\text{map}(f, x) is equal to the image under ff of the finite set of charges for those same terms in the original spectrum xx. That is, set(phenoConstrainingChargesSP(map(f,x)))=f(set(phenoConstrainingChargesSP(x))) \text{set}(\text{phenoConstrainingChargesSP}(\text{map}(f, x))) = f(\text{set}(\text{phenoConstrainingChargesSP}(x))) where phenoConstrainingChargesSP\text{phenoConstrainingChargesSP} denotes the multiset of charges resulting from the superpotential terms μ,β,Λ,W1,W2,\mu, \beta, \Lambda, W_1, W_2, and W4W_4 (which lead to proton decay or R-parity violation), and set()\text{set}(\cdot) denotes the conversion of a multiset to a finite set.

theorem

If xx generates dangerous terms at level nn, then map(f,x)\text{map}(f, x) generates dangerous terms at level nn

#map_yukawaGeneratesDangerousAtLevel

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z} and any natural number nn, if the spectrum xx regenerates a phenomenologically constrained (dangerous) superpotential term through the insertion of up to nn Yukawa-related singlets, then the mapped charge spectrum map(f,x)\text{map}(f, x) also regenerates a dangerous superpotential term at the same level nn. Mathematically, if Yn(x)P(x)Y_n(x) \cap P(x) \neq \emptyset, where Yn(x)Y_n(x) is the set of charges formed by summing up to nn Yukawa charges and P(x)P(x) is the set of phenomenologically constraining charges, then Yn(map(f,x))P(map(f,x))Y_n(\text{map}(f, x)) \cap P(\text{map}(f, x)) \neq \emptyset.

theorem

If map(f,x)\text{map}(f, x) does not generate dangerous terms at level nn, then xx does not

#not_yukawaGeneratesDangerousAtLevel_of_map

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids representing charge groups, and let f:ZZ1f: \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. For any SU(5)SU(5) charge spectrum xx defined over Z\mathcal{Z} and any natural number nn, if the mapped charge spectrum map(f,x)\text{map}(f, x) does not regenerate a phenomenologically constrained (dangerous) superpotential term through the insertion of up to nn Yukawa-related singlets, then the original charge spectrum xx also does not regenerate a dangerous superpotential term at level nn. Mathematically, this states that if Yn(map(f,x))P(map(f,x))=Y_n(\text{map}(f, x)) \cap P(\text{map}(f, x)) = \emptyset, then Yn(x)P(x)=Y_n(x) \cap P(x) = \emptyset, where YnY_n denotes the multiset of charges from nn Yukawa insertions and PP denotes the set of phenomenologically constrained charges.

The image of yy under ff is equal to xx. That is, f~(hd)=qHd\tilde{f}(h_d) = q_{H_d}, f~(hu)=qHu\tilde{f}(h_u) = q_{H_u}, f(P5ˉ)=Q5ˉf(P_{\bar{5}}) = Q_{\bar{5}}, and f(P10)=Q10f(P_{10}) = Q_{10}, where f~\tilde{f} is the extension of ff to handle optional charges (mapping none\text{none} to none\text{none}). 2. The components of yy are restricted such that hd,huS5{none}h_d, h_u \in S_5 \cup \{\text{none}\}, P5ˉS5P_{\bar{5}} \subseteq S_5, and P10S10P_{10} \subseteq S_{10}. This set corresponds to the preimage of xx under the mapping induced by ff, restricted to the subset of spectra whose matter and Higgs charges are contained within S5S_5 and S10S_{10}.

(Note: ofFinset(S5ˉ,S10)\text{ofFinset}(S_{\bar{5}}, S_{10}) is the set of spectra whose components are restricted such that the Higgs charges are in S5ˉ{none}S_{\bar{5}} \cup \{\text{none}\}, and the matter charge sets Q5ˉQ_{\bar{5}} and Q10Q_{10} are subsets of S5ˉS_{\bar{5}} and S10S_{10} respectively.)

#preimageOfFinsetCard

Let Z\mathcal{Z} and Z1\mathcal{Z}_1 be additive monoids, and let f:ZZ1f : \mathcal{Z} \to \mathcal{Z}_1 be an additive monoid homomorphism. Given finite sets of charges S5,S10ZS_5, S_{10} \subset \mathcal{Z} and a target charge spectrum x=(qHd,qHu,Q5,Q10)x = (q_{H_d}, q_{H_u}, Q_5, Q_{10}) defined over Z1\mathcal{Z}_1, this function computes the cardinality of the preimage of xx under the mapping ff within a restricted set of spectra. Specifically, it calculates the number of charge spectra yy over Z\mathcal{Z} such that y.map(f)=xy.\text{map}(f) = x, where the Higgs charges of yy are restricted to S5{none}S_5 \cup \{\text{none}\} and the sets of charges for the matter fields are subsets of S5S_5 and S10S_{10} respectively. The value is computed as the product of: - The number of elements hdS5{none}h_d \in S_5 \cup \{\text{none}\} such that f(hd)=qHdf(h_d) = q_{H_d}. - The number of elements huS5{none}h_u \in S_5 \cup \{\text{none}\} such that f(hu)=qHuf(h_u) = q_{H_u}. - The number of subsets P5S5P_5 \subseteq S_5 such that the image f(P5)=Q5f(P_5) = Q_5. - The number of subsets P10S10P_{10} \subseteq S_{10} such that the image f(P10)=Q10f(P_{10}) = Q_{10}.
