Flavour violation in supersymmetric theories

open access: yesNuclear Physics B, 1985
Abstract We investigate in detail the question of lepton-flavour violation in a SU(2) × U(1) supersymmetric model, where the breaking of supersymmetry (SUSY) is achieved through the coupling to N = 1 supergravity. It is shown that in the limit of degenerate neutrino masses, lepton flavour is exactly conserved.

Flavour mixing transport theory and resonant leptogenesis [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We derive non-equilibrium quantum transport equations for flavour-mixing fermions. We develop the formalism mostly in the context of resonant leptogenesis with two mixing Majorana fermions and one lepton flavour, but our master equations are valid more generally in homogeneous and isotropic systems.

Modular binary octahedral symmetry for flavor structure of Standard Model

open access: yesJournal of High Energy Physics, 2023
We have investigated the modular binary octahedral group 2O as a flavor symmetry to explain the structure of Standard Model. The vector-valued modular forms in all irreducible representations of this group are constructed. We have classified all possible

Quarks at the modular S 4 cusp

open access: yesJournal of High Energy Physics, 2023
We analyse the possibility of describing quark masses, mixing and CP violation in S 4 ′ $$ {S}_4^{\prime } $$ modular flavour models without flavons. We focus on the case where the closeness of the modulus to the point of residual ℤ 3 ST $$ {\mathbb{Z ...

Fermion hierarchies in SU(5) grand unification from Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry

open access: yesJournal of High Energy Physics, 2023
We construct an SU(5) grand unified model in which the hierarchies of the quark and lepton masses and mixing are explained by the Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry.

CKM substructure from the weak to the Planck scale

open access: yesJournal of High Energy Physics, 2022
We look for relations among CKM matrix elements that are not consequences of the Wolfenstein parametrization. In particular, we search for products of CKM elements raised to integer powers that approximately equal 1.
