We explore how quantum gravity effects, manifested through the breaking of discrete
symmetry responsible for both dark matter and domain walls, can have observational effects …

A bstract We study a scenario where both dark matter and heavy right handed neutrino
(RHN) responsible for leptogenesis acquire masses by crossing the relativistic bubble walls …

We perform a model independent study of freeze-in of massive particle dark matter (DM) by
adopting an effective field theory framework. Considering the dark matter to be a gauge …

We study a minimal scenario to realize nonthermal leptogenesis and UV freeze-in of a
Standard Model (SM) gauge singlet fermionic dark matter (DM) simultaneously, with inflaton …

We consider a U (1) X⊗ Z 2⊗ Z 2′ extension of the Standard Model (SM), where the U (1) X
charge of an SM field is given by a linear combination of its hypercharge and B− L number …

We explore the phenomenological consequences of breaking discrete global symmetries in
quantum gravity (QG). We extend a previous scenario where discrete global symmetries are …

We propose a new gauged BL BL extension of the standard model where light neutrinos are
of Dirac type, naturally acquiring sub-eV mass after electroweak symmetry breaking, without …

A bstract We consider an extension of the Standard Model that explains the neutrino masses
and has a rich dark matter phenomenology. The model has two dark matter candidates, a …

A bstract We investigate ways of identifying two kinds of dark matter (DM) component
particles at high-energy colliders. The strategy is to notice and distinguish double-peaks …

If coupled feebly to the Standard Model bath, dark matter can evade the severe constraints
from the direct search experiments. At the same time, such interactions help produce dark …
