Aspects of flavour and supersymmetry in F-theory GUTs [PDF]

Journal of High Energy Physics, 2010
We study the constraints of supersymmetry on flavour in recently proposed models of F-theory GUTs. We relate the topologically twisted theory to the canonical presentation of eight-dimensional super Yang-Mills and provide a dictionary between the two.

Modular A5 symmetry for flavour model building [PDF]

Journal of High Energy Physics, 2018
In the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A5.

Accidental SO(10) axion from gauged flavour [PDF]

Journal of High Energy Physics, 2020
An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3)f flavour group. The PQ symmetry is protected by the ℤ4 × ℤ3 center of SO(10) × SU(3)f up to effective operators of canonical ...

SPONTANEOUS CP IN A SUSY THEORY OF FLAVOUR

String Phenomenology 2003, 2004
We present a model based on an SU(3) family symmetry providing a full description of quark and lepton masses and mixing angles. CP is spontaneously broken in the flavour sector reproducing the observed results of the Jarlskog invariant in the CKM mixing matrix.

Modular binary octahedral symmetry for flavor structure of Standard Model

Journal 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

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

Journal 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.

Phases of 2d gauge theories and symmetric mass generation [PDF]

Journal of High Energy Physics
We study the dynamics and phase structure of Abelian gauge theories in d = 1 + 1 dimensions. These include U(1) gauge theory coupled to a scalar and a fermion, as well as the two-flavour Schwinger model with different charges.

Flavour mixing transport theory and resonant leptogenesis [PDF]

Journal 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.

CKM substructure from the weak to the Planck scale

Journal 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.
