We study the possibility of cogenesis of baryon and dark matter (DM) from the out-of-
equilibrium CP violating decay of right handed neutrino (RHN) that are dominantly of non …

We show that the type-I seesaw, responsible for generating the light neutrino mass, itself is
capable of accommodating one of the three right handed neutrinos as a freeze-in type of …

With entropy injection, an early matter-dominated epoch (EMD) impels the axion decay
constant fa toward larger values to produce correct axion dark matter (DM) abundance …

A bstract We explore the possibility of having a fermionic dark matter candidate within U
(1)′ models for CEνNS experiments in light of the latest COHERENT data and the current …

Since the gravitational interaction is universal, any particle that ever existed, if kinematically
accessible, has to be produced through her. We explore the possibility that dark matter is …

A bstract The low-energy U (1) B− L gauge symmetry is well-motivated as part of beyond
Standard Model physics related to neutrino mass generation. We show that a light B− L …

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 …

A bstract We apply the multiple point criticality principle to inflationary model building and
study Coleman-Weinberg inflation when the scalar potential is quadratic in the logarithmic …

We propose a scenario where dark matter (DM) can be generated nonthermally due to the
presence of a light Dirac neutrino portal between the standard model (SM) and dark sector …

A bstract We propose a mechanism for cogenesis of baryon and dark matter (DM) in the
universe via the Affleck-Dine (AD) route. An AD field which breaks the lepton number …
