Approaching minimal flavour violation from an SU(5) × S4 × U(1) SUSY GUT

Approaching minimal flavour violation from an SU(5) × S4 × U(1) SUSY GUT
Approaching minimal flavour violation from an SU(5) × S4 × U(1) SUSY GUT
We show how approximate Minimal Flavour Violation (MFV) can emerge from an SU(5) Supersymmetric Grand Unified Theory (SUSY GUT) supplemented by an S 4 × U(1) family symmetry, which provides a good description of all quark and lepton (including neutrino) masses, mixings and CP violation. Assuming a SUSY breaking mechanism which respects the family symmetry, we calculate in full explicit detail the low energy mass insertion parameters in the super-CKM basis, including the effects of canonical normalisation and renormalisation group running. We find that the very simple family symmetry S 4 ×U(1) is sufficient to approximately reproduce the effects of low energy MFV.

Abstract

We show how approximate Minimal Flavour Violation (MFV) can emerge from an SU(5) Supersymmetric Grand Unified Theory (SUSY GUT) supplemented by an S 4 × U(1) family symmetry, which provides a good description of all quark and lepton (including neutrino) masses, mixings and CP violation. Assuming a SUSY breaking mechanism which respects the family symmetry, we calculate in full explicit detail the low energy mass insertion parameters in the super-CKM basis, including the effects of canonical normalisation and renormalisation group running. We find that the very simple family symmetry S 4 ×U(1) is sufficient to approximately reproduce the effects of low energy MFV.
