Twin Pati-Salam theory of flavour with a TeV scale vector leptoquark [PDF]

Journal of High Energy Physics, 2021
Abstract We propose a twin Pati-Salam (PS) theory of flavour broken to the G4321 gauge group at high energies, then to the Standard Model at low energies, yielding a TeV scale vector leptoquark $$ {U}_1^{\mu } $$ U 1 μ (

Modular flavor symmetries and fermion mass hierarchies

Journal of High Energy Physics
We investigate fermion mass hierarchies in models with modular flavor symmetries. Several key conclusions arise from the observation that the determinants of mass matrices transform as 1-dimensional vector-valued modular forms. We demonstrate that, under

Lepton Electric Dipole Moments from Heavy States Yukawa Couplings

, 2003
In supersymmetric theories the radiative corrections due to heavy states could leave their footprints in the flavour structure of the supersymmetry breaking masses.

Towards predictive flavour models in SUSY SU(5) GUTs with doublet-triplet splitting [PDF]

, 2014
We discuss how the double missing partner mechanism solution to the doublet-triplet splitting problem in four-dimensional supersymmetric SU(5) Grand Unified Theories (GUTs) can be combined with predictive models for the quark-lepton Yukawa coupling ...

Can gauge theories of flavour be accessible at the LHC? [PDF]

Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018
Horizontal gauge symmetries between fermion families and their spontaneous breaking can be at the origin of the inter-family mass hierarchies. The corresponding gauge bosons must have flavor changing couplings to fermions and generically the very stringent limits on their masses arise from flavour changing phenomena and CP-violation.

SUSY Seesaw and FCNC

, 2004
After a quarter of century of intense search for new physics beyond the Standard Model (SM), two ideas stand out to naturally cope with (i) small neutrino masses and (ii) a light higgs boson : Seesaw and SUSY.

Superconformal field theory in three dimensions: Correlation functions of conserved currents [PDF]

, 2015
For N-extended superconformal field theories in three spacetime dimensions (3D), with N=1,2,3, we compute the two- and three-point correlation functions of the supercurrent and the flavour current multiplets.

Supersymmetric Casimir Energy and $\mathrm{SL(3,\mathbb{Z})}$ Transformations

, 2016
We provide a recipe to extract the supersymmetric Casimir energy of theories defined on primary Hopf surfaces directly from the superconformal index. It involves an $\mathrm{SL(3,\mathbb{Z})}$ transformation acting on the complex structure moduli of the ...

Signals of Supersymmetric Flavour Models in B Physics [PDF]

, 2001
If the mechanism of Supersymmetry breaking is not flavour blind, some flavour symmetry is likely to be needed to prevent excessive flavour changing neutral current effects.
