Yukawa charges

i. Overview

In this module we look at the charges associated with the Yukawa terms in the super potential, and when they can regenerate phenomenologically constrained super-potential terms at different levels.

We do not not consider the regeneration of terms in the Kähler potential within this module.

ii. Key results

• ofYukawaTerms: the multiset of charges associated with the Yukawa terms
• ofYukawaTermsNSum: the multiset of charges associated with up-to n copies of the Yukawa terms or equivalently the charges of singlet insertions needed to regenerate Yukawa terms.
• YukawaGeneratesDangerousAtLevel: the proposition that a charge spectrum regenerates a phenomenologically constrained term in the super-potential with up-to n insertions of singlets needed to regenerate the Yukawa terms.

A. Charges of the Yukawa terms

def SuperSymmetry.SU5.ChargeSpectrum.ofYukawaTerms {𝓩 : Type} [AddCommGroup 𝓩] (x : ChargeSpectrum 𝓩) : Multiset 𝓩

The collection of charges associated with Yukawa terms. Correspondingly, the (negative) of the charges of the singlets needed to regenerate all Yukawa terms in the potential.

• x.ofYukawaTerms = x.ofPotentialTerm' SuperSymmetry.SU5.PotentialTerm.topYukawa + x.ofPotentialTerm' SuperSymmetry.SU5.PotentialTerm.bottomYukawa

def SuperSymmetry.SU5.ChargeSpectrum.ofYukawaTermsNSum {𝓩 : Type} [AddCommGroup 𝓩] (x : ChargeSpectrum 𝓩) : ℕ → Multiset 𝓩

The charges of those terms which can be regenerated with up-to n insertions of singlets needed to regenerate the Yukawa terms. Equivalently, the sum of up-to n integers each corresponding to a charge of the Yukawa terms.

For charges x : Charges, the proposition which states that the singlets needed to regenerate the Yukawa couplings regenerate a dangerous coupling (in the superpotential) with up-to n insertions of the scalars.

Note: If defined as (x.ofYukawaTermsNSum n).toFinset ∩ x.phenoConstrainingChargesSP.toFinset ≠ ∅ the execution time is greatly increased.
