A bstractWe discuss gauge coupling unification of SU(3)C × SU(2)L × U(1)Y descending directly from non-supersymmetric SO(10) while providing solutions to the three out-standing problems of the standard model: neutrino masses, dark matter, and the baryon asymmetry of the universe. Conservation of matter parity as gauged discrete symmetry for the stability and identification of dark matter in the model calls for high-scale spontaneous symmetry breaking through 126H Higgs representation. This… 
Triplet leptogenesis, type-II seesaw dominance, intrinsic dark matter, vacuum stability and proton decay in minimal SO(10) breakings
We implement type-II seesaw dominance for neutrino mass and baryogenesis through heavy scalar triplet leptogenesis in a class of minimal non-supersymmetric SO(10) models where matter parity as
Unification predictions with or without supersymmetry
Supersymmetric (SUSY) grand unified theories (GUTs) appear to be best motivated for understanding strong, weak and electromagnetic interactions of nature. We briefly review emergence of new formulas
Neutrino Mass, Coupling Unification, Verifiable Proton Decay, Vacuum Stability, and WIMP Dark Matter in SU(5)
Nonsupersymmetric minimal SU(5) with Higgs representations 24H and 5H and standard fermions in 5¯F⊕10F is well known for its failure in unification of gauge couplings and lack of predicting neutrino
Asymmetric dark matter models in SO(10)
We systematically study the possibilities for asymmetric dark matter in the context of non-supersymmetric SO(10) models of grand unification. Dark matter stability in SO(10) is guaranteed by a

Neutrinoless double beta decay and Sterile dark matter in extended left right symmetric model
We have studied a flavor symmetry based extended left-right symmetric model(LRSM) with dominant type-II seesaw mechanism and have explored the associated neutrino phenomenology. The particle content
Vanishing threshold uncertainties and prediction for proton decay in non-supersymmetric $E_6$ GUT with intermediate trinification symmetry
We consider a class of non-supersymmetric $E_6$ Grand Unified Theories (GUTs) with trinification symmetry $SU(3)_C \times SU(3)_L \times SU(3)_R\times D$ ($D$ denoted as D-parity for discrete
Importance of generalized μτ symmetry and its CP extension on neutrino mixing and leptogenesis
Abstract Within the framework of residual symmetry, two ℤ 2 type associate μτ inter- change symmetries robustly constrain the Dirac CP phase δ in a model independent way. Both of them predict


A neutrino mass-mixing sum rule from SO(10) and neutrinoless double beta decay
A bstractMinimal SO(10) grand unified models provide phenomenological predictions for neutrino mass patterns and mixing. These are the outcome of the interplay of several features, namely: i) the
Unification of gauge couplings in radiative neutrino mass models
A bstractWe investigate the possibility of gauge coupling unification in various radiative neutrino mass models, which generate neutrino masses at one- and/or two-loop level. Renormalization group
Minimal SUSY SO(10) model and predictions for neutrino mixings and leptonic CP violation
We discuss a minimal supersymmetric SO(10) model where $B\ensuremath{-}L$ symmetry is broken by a 126 dimensional Higgs boson multiplet which also contributes to fermion masses in conjunction with a
