Leptogenesis is a class of scenarios in which the cosmic baryon asymmetry originates from
an initial lepton asymmetry generated in the decays of heavy sterile neutrinos in the early …

Flavor effects can have a significant impact on the final estimate of the lepton (and therefore
baryon) asymmetry in scenarios of leptogenesis. It is therefore necessary to account fully for …

Recent evidence for neutrino masses has established the leptogenesis mechanism as a
very natural possible explanation for the baryon asymmetry of the Universe. The explicit …

A bstract We revisit a class of supersymmetric SO (10) models with tb-τ Yukawa coupling
unification condition, with emphasis on the prediction of the Higgs mass. We discuss …

A bstract We present a flavour-covariant formalism for scalar triplet leptogenesis, which
takes into account the effects of the different lepton flavours in a consistent way. Our main …

We study flavour violation in a supersymmetric SO (10) implementation of the type II seesaw
mechanism, which provides a predictive realization of triplet leptogenesis. The experimental …

The tb-τ unification with positive Higgs mass parameter μ in the minimal supersymmetric
standard model prefers “just so” Higgs splitting and a light gluino≲ 500 GeV which appears …

We explore the low-scale implications of the Pati-Salam Model including the TeV scale right-
handed neutrinos interacting and mixing with the MSSM fields through the inverse seesaw …

We propose a new scheme in which supersymmetry breaking is communicated to the MSSM
sfermions by GUT gauge interactions at the tree level. The (positive) contribution of MSSM …

Tree level gauge mediation (TGM) may be considered as the simplest way to communicate
supersymmetry breaking: through the tree level renormalizable exchange of heavy gauge …
