▪ Abstract We review the present state and future outlook of our understanding of neutrino
masses and mixings. We discuss what we think are the most important perspectives on the …

A broad overview of the current status of proton stability in unified models of particle
interactions is given which includes non-supersymmetric unification, SUSY and SUGRA …

This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the
theoretical, phenomenological and experimental issues related to flavor phenomena in the …

This is a review article about neutrino mass models, particularly see-saw models involving
three active neutrinos that are capable of describing both the atmospheric neutrino …

Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

We present the various leptogenesis scenarios which may occur if, in addition to the
ordinary heavy right-handed neutrinos, there exists a heavy scalar SU (2) L triplet coupled to …

We discuss a minimal supersymmetric SO (10) model where B− L symmetry is broken by a
126 dimensional Higgs boson multiplet which also contributes to fermion masses in …

We examine many SO (10) models for their viability or otherwise in explaining all the fermion
masses and mixing angles. This study is carried out for both supersymmetric and …

A bstract We investigate the Yukawa coupling unification for the third generation in a class of
SO (10) unified models which are consistent with the 4.2 σ deviation from the standard …

The constraints of gauge unification on intermediate mass scales in nonsupersymmetric SO
(10) scenarios are systematically discussed. With respect to the existing reference studies …
