In SO(10), the type-I and type-II see-saw scales ≥ 1012 GeV are far away from being probed by direct experimental tests. In the absence of supersymmetry, we show how experimentally verifiable radiative see-saw formula of Ma type is realized in non-

High energy accelerators may probe into the dark matter and the seesaw neutrino mass scales if they are not much heavier than ∼ O ( TeV ) . In the absence of supersymmetry, we extend a class of minimal SO ( 10 ) models to predict well-known cold da

It is shown that a supersymmetric SO(10) model extended with fermion singlets can accommodate the observed neutrino masses and mixings as well as generate the desired lepton asymmetry in concordance with the gravitino constraint. A necessary predicti

Recently type-II seesaw in a supersymmetric$SO(10)$ framework has been found useful in explaining large solar and atmospheric mixing angles as well as a larger value of ${\ensuremath{\theta}}_{13}$ while unifying quark and lepton masses. An important

We show how gauge coupling unification is successfully implemented through non-supersymmetric grand unified theory, $SO(10)\times G_f (~G_f=S_4, SO(3)_f, SU(3)_f)$, using low-scale flavor symmetric model of the type $SU(2)_L\times U(1)_Y$ $ \times SU

We explore the prospects of low-scale leptogenesis in a class of supersymmetric SO(10) models using extra singlet neutrinos (T i , i=1, 2, 3) and the Higgs representations 126 H ⊕ 126 H as well as 16 H ⊕16 H . A singlet neutrino, which we show ca

A low intermediate scale within minimal supersymmetric $SO(10)$ GUTs is a desirable feature to accommodate leptogenesis. We explore this possibility in models where the intermediate gauge symmetry breaks spontaneously by (a) doublet Higgs scalars and

The high scale mixing unification hypothesis recently proposed by three of us (R. N. M., M. K. P. and G. R.) states that if at the seesaw scale, the quark and lepton mixing matrices are equal then for quasi-degenerate neutrinos, radiative corrections

Radiative corrections to neutrino mixings in seesaw models depend on the nature of new physics between the weak and the GUT-seesaw scales and can be taken into account using the renormalization group equations. This new physics effect becomes particu

A new method of left-right symmetry breaking which decouples parity and SU(2) R -breaking scales is found to yield several interesting observable consequences for grand unification symmetries like SU(16) and SU(8) L ×SU(8) R . Certain scenarios in S
