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.

Plan B: new Z′ models for b → sℓ + ℓ − anomalies

Journal of High Energy Physics, 2023
Measurements of b → sμ + μ − transitions indicate that there may be a new physics field coupling to di-muon pairs associated with the b to s flavour transition.

Fermion masses, critical behavior and universality

Journal of High Energy Physics, 2023
We look for signals of critical behavior in the Yukawa sector. By reviewing a set of models for the fermion masses, we select those where a symmetry-breaking order parameter sits at a transition point between a disordered phase and an ordered one.

Littlest modular seesaw

Journal of High Energy Physics, 2023
We present the first complete model of the Littlest Modular Seesaw, based on two right-handed neutrinos, within the framework of multiple modular symmetries, justifying the use of multiple moduli fields which take their values at 3 specific stabilizers ...

Local Search For Satisfiability Modulo Integer Arithmetic Theories [PDF]

ACM Transactions on Computational Logic, 2022
Satisfiability Modulo Theories (SMT) refers to the problem of deciding the satisfiability of a formula with respect to certain background first-order theories.

Minimally modified Fritzsch texture for quark masses and CKM mixing

Journal of High Energy Physics, 2023
The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling.

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 ...

Common origin of θ 13 and dark matter within the flavor symmetric scoto-seesaw framework

Journal of High Energy Physics, 2022
To understand the observed pattern of neutrino masses and mixing as well as to account for the dark matter we propose a hybrid scoto-seesaw model based on the A 4 discrete flavor symmetry.

Constraining flavour patterns of scalar leptoquarks in the effective field theory [PDF]

Journal of High Energy Physics, 2021
Abstract We investigate the viability of extending the Standard Model with S1 and S3 scalar leptoquarks when the flavour structure is parametrized in terms of Froggatt-Nielsen charges. In contrast to a similar analysis with a vector leptoquark, we find essentially two solutions for the charges that fit the experimental constraints,
