Non-CKM induced flavor violation in "minimal" SUSY SU(5) models

TL;DR

This paper examines how neutrino Yukawa couplings induce flavor violation in minimal SUSY SU(5) models with nonrenormalizable operators, analyzing different seesaw mechanisms to understand their effects on flavor physics.

Contribution

It provides a detailed analysis of flavor violation patterns in minimal SUSY SU(5) models incorporating nonrenormalizable operators and compares three seesaw mechanisms.

Findings

Neutrino Yukawa couplings induce flavor violation in these models.

Different seesaw mechanisms lead to distinct flavor violation patterns.

Results inform constraints on SUSY GUT models from flavor physics.

Abstract

Patterns of flavor violation induced by neutrino Yukawa couplings are discussed in realistic ``minimal'' SUSY SU(5) models, obtained by adding nonrenormalizable operators to the minimal one, in order to fix the fermion spectrum and suppress proton decay. Results are presented for the three possible implementations of the seesaw mechanisms, i.e. of Type I, II and III.
