Pheno constrained charge spectra
i. Overview
We define a predicate `IsPhenoConstrained` on `ChargeSpectrum 𝓩` which is true if the charge spectrum allows any super-potential or Kähler potential term leading to proton decay or R-parity violation.
We prove basic properties of this predicate including monotonicity.
We define some variations of this result.
ii. Key results
- `IsPhenoConstrained`: The predicate defining a pheno-constrained charge spectrum as one allowing any term leading to proton decay or R-parity violation. - `phenoConstrainingChargesSP`: The multiset of charges of terms in the super-potential leading to a pheno-constrained charge spectrum. - `IsPhenoConstrainedQ5`: The predicate defining when a charge spectrum becomes pheno-constrained after adding a single charge to the `Q5` set. - `IsPhenoConstrainedQ10`: The predicate defining when a charge spectrum becomes pheno-constrained after adding a single charge to the `Q10` set.

Phenomenologically constrained charge spectrum
Let be a charge spectrum over a group . The predicate `IsPhenoConstrained` is true for if allows any of the following terms: , or . Mathematically, this is defined as the disjunction: In the context of SU(5) supersymmetry, these terms correspond to operators in the superpotential or Kähler potential that lead to proton decay or R-parity violation.
Decidability of whether a charge spectrum is phenomenologically constrained
Let be a group with decidable equality and be a charge spectrum over . The property that is phenomenologically constrained, denoted as , is decidable. This predicate is defined as the disjunction of whether the spectrum allows any of the following terms: In the context of SU(5) supersymmetry, these terms correspond to operators in the superpotential or Kähler potential that lead to proton decay or R-parity violation.
The empty charge spectrum is not phenomenologically constrained
The empty charge spectrum over a group is not phenomenologically constrained. That is, the predicate `IsPhenoConstrained` is false for the spectrum containing no charges.
Monotonicity of the phenomenologically constrained property of charge spectra
Let and be charge spectra over a group . If is a subset of () and is phenomenologically constrained, then is also phenomenologically constrained. A charge spectrum is phenomenologically constrained if it allows any of the terms , or , which correspond to superpotential or Kähler potential operators leading to proton decay or R-parity violation.

Phenomenological constraint of a charge spectrum with additional charge

For a charge spectrum and a charge , the condition that the addition of to the set of makes the spectrum phenomenologically constrained (denoted by `IsPhenoConstrainedQ5`) is equivalent to the spectrum allowing at least one of the following physical terms: or . That is,
Decidability of `IsPhenoConstrainedQ5` for a charge spectrum and charge
For a given charge spectrum and a charge , the predicate `IsPhenoConstrainedQ5` is decidable. This means there is an algorithmic procedure to determine whether the addition of the charge to the spectrum allows terms in the superpotential or Kähler potential—specifically , or —that lead to phenomenological issues such as proton decay or R-parity violation.

Let be a charge spectrum over a group . For any charge , the charge spectrum is phenomenologically constrained if and only if either the addition of to satisfies the predicate `IsPhenoConstrainedQ5` or the original spectrum is already phenomenologically constrained.

Given a charge spectrum and a specific charge (representing a charge in the representation of ), the proposition `IsPhenoConstrainedQ10` is true if the inclusion of allows at least one of the following terms in the superpotential or Kähler potential: , or . These terms typically correspond to operators that lead to proton decay or R-parity violation in the phenomenological analysis of the model.

Decidability of whether is phenomenologically constrained by
For a given charge spectrum and a specific charge (representing a charge in the representation of ), the property that the spectrum is phenomenologically constrained by (denoted as ) is decidable.
