Complete of nonPhenoConstrainedCharges I #

We show that the nonPhenoConstrainedCharges I is complete, that is, it contains every charge in ofFinset I.allowedBarFiveCharges I.allowedTenCharges which is not pheno-constrained, permits a top yukawa and is complete.

Method #

The method of our proof is the following.

  1. We define completionTopYukawa which contains all completions of elements which minimally allow the top Yukawa, which are not pheno-constrained. We show that every charge in ofFinset I.allowedBarFiveCharges I.allowedTenCharges which is not pheno-constrained and complete must contain an element of completionTopYukawaSame as a subset.
  2. We show that completionTopYukawa I is a subset of nonPhenoConstrainedCharges I.
  3. We then use the fact that one can not add to any charge in nonPhenoConstrainedCharges another Q5 or Q10 without remaining in nonPhenoConstrainedCharges or allowing a pheno-constraining term to be present.

This proof of completeness is more like a certification of completeness, rather than a constructive proof.
