We analyze the effect of the Dark-large mixing angle (DLMA) solution on the effective Majorana mass (m??) governing neutrino-less double beta decay (0???) in the presence of a sterile neutrino. We consider the 3+1 picture, ...

The heavy quark drag and momentum diffusion have been investigated in a hot magnetized quark-gluon plasma, along the directions parallel and perpendicular to the magnetic field. The analysis is done within the framework ...

General relativity may be an effective theory with higher curvature correction terms in the action. Inclusion of these terms leads to exciting new possibilities, e.g., gravitational and electromagnetic perturbations following ...

We explore the challenging but phenomenologically interesting hierarchical mass spectrum of Inert Doublet Model where relatively light dark matter along with much heavier scalar states can fully satisfy the constraints on ...

The Experiment to Detect the Global Epoch of reionization Signature (EDGES) collaboration has reported an excess absorption dip in the 21 cm signal during cosmic dawn era. The stronger than expected 21 absorption signal ...

We investigate the consequences of ??? reflection symmetry in presence of a light sterile neutrino for the 3+1 neutrino mixing scheme. We discuss the implications of total ??? reflection symmetry as well partial ??? ...
