SO(10) × S4 grand unified theory of flavour and leptogenesis

Journal of High Energy Physics, 2017
Abstract We propose a Grand Unified Theory of Flavour, based on SO(10) together with a non-Abelian discrete group S4, under which the unified three quark and lepton 16-plets are unified into a single triplet 3′. The model involves a further discrete group ℤ 4 R

Twistor Strings with Flavour [PDF]

, 2007
We explore the tree-level description of a class of N=2 UV-finite SYM theories with fundamental flavour within a topological B-model twistor string framework.

Exotic particles below the TeV from low scale flavour theories [PDF]

, 2010
A flavour gauge theory is observable only if the symmetry is broken at relatively low energies. The intrinsic parity-violation of the fermion representations in a flavour theory describing quark, lepton and higgsino masses and mixings generically ...

Microscopic Dirac Spectrum in a 2d Gauge Theory with Zero Chiral Condensate

, 2013
Fermionic theories with a vanishing chiral condensate (in the chiral limit) have recently attracted considerable interest; in particular variants of multi-flavour QCD are candidates for this behaviour.

Predicting the Sparticle Spectrum from GUTs via SUSY Threshold Corrections with SusyTC [PDF]

, 2015
Grand Unified Theories (GUTs) can feature predictions for the ratios of quark and lepton Yukawa couplings at high energy, which can be tested with the increasingly precise results for the fermion masses, given at low energies.

From Nonstandard Analysis to Various Flavours of Computability Theory [PDF]

, 2017
As suggested by the title, it has recently become clear that theorems of Nonstandard Analysis (NSA) give rise to theorems in computability theory (no longer involving NSA). Now, the aforementioned discipline divides into classical and higher-order computability theory, where the former (resp.

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.

6d SCFTs and U(1) flavour symmetries [PDF]

Journal of High Energy Physics, 2018
A bstractWe study the behaviour of abelian gauge symmetries in six-dimensional N = (1,0) theories upon decoupling gravity and investigate abelian flavour symmetries in the context of 6d N = (1, 0) SCFTs.

Renormalization of lattice gauge theories with massless Ginsparg Wilson fermions

, 1999
Using functional techniques, we prove, to all orders of perturbation theory, that lattice vector gauge theories with Ginsparg Wilson fermions are renormalizable. For two or more massless fermions, they satisfy a flavour mixing axial vector Ward identity.

Supersymmetric Higgs Singlet Effects on B-Meson FCNC Observables at Large tan(beta) [PDF]

, 2008
Higgs singlet superfields are usually present in most extensions of the Minimal Supersymmetric Standard Model (MSSM) that address the mu-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric ...
