Lepton mass textures from non-invertible multiplication rules
Journal of High Energy PhysicsWe study the lepton mass textures, which are derived by ℤ 2 gauging of ℤ M symmetries. We can obtain various textures for the Yukawa couplings in the charged lepton sector, but the patterns of neutrino mass matrices are limited. All the obtained textures

Strangeness in the Meson Cloud Model
, 2010 I review progress in calculating strange quark and antiquark distributions of the nucleon using the meson cloud model. This progress parallels that of the meson cloud model, which is now a useful theoretical basis for understanding symmetry breaking in ...

Breaking Standard Model global symmetries with the tau lepton
SciPost Physics ProceedingsProperties of the dynamics of the Standard Model processes such as lepton flavour preservation and lepton, or baryon, number conservation, are usually taken for granted.

LFV and Dipole Moments in Models with A4 Flavour Symmetry
, 2009 It is presented an analysis on lepton flavour violating transitions, leptonic magnetic dipole moments and electric dipole moments in a class of models characterized by the flavour symmetry A4 x Z3 x U(1)_FN, whose choice is motivated by the approximate ...

A global analysis of the SMEFT under the minimal MFV assumption
Journal of High Energy PhysicsWe present comprehensive global fits of the SMEFT under the minimal minimal flavour violation (MFV) hypothesis, i.e. assuming that only the flavour-symmetric and CP-invariant operators are relevant at the high scale.

Direct and indirect signals of natural composite Higgs models
, 2015 We present a comprehensive numerical analysis of a four-dimensional model with the Higgs as a composite pseudo-Nambu-Goldstone boson that features a calculable Higgs potential and protective custodial and flavour symmetries to reduce electroweak fine ...

Minimal Resonant Leptogenesis and Lepton Flavour Violation
, 2012 We discuss minimal non-supersymmetric models of resonant leptogenesis, based on an approximate flavour symmetries. As an illustrative example, we consider a resonant tau-leptogenesis model, compatible with universal right-handed neutrino masses at the ...
