Neutrino Mass Matrices in Models with Horizontal Symmetries
Asim K. Ray, Utpal Sarkar
We have studied the most general neutrino mass matrices in models with SU(2) and SU(3) horizontal symmetries. Without going into the details of the models it is possible to write d…

New Dimensions New Hopes
Utpal Sarkar
We live in a four dimensional world. But the idea of unification of fundamental interactions lead us to higher dimensional theories. Recently a new theory with extra dimensions has…

Supersymmetric Model of Neutrino Mass and Leptogenesis with String-Scale Unification
Biswajoy Brahmachari, Ernest Ma, Utpal Sarkar
Adjoint supermultiplets (1,3,0) and (8,1,0) modify the evolution of gauge couplings. If the unification of gauge couplings occurs at the string scale, their masses are fixed at aro…
