The basic idea of this work is to achieve the observed relic density of a non-thermal dark
matter (DM) and its connection with Cosmic Microwave Background (CMB) via additional …

Dynamical Chern-Simons (dCS) gravity is a four-dimensional parity-violating extension of
general relativity. The standard mechanism to obtain this extension predicts negligible …

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 …

The model-independent theoretical upper bound on the thermal dark matter (DM) mass can
be derived from the maximum inelastic DM cross section featuring the whole observed DM …

In this paper, we construct a viable model for a GeV scale self-interacting dark matter (DM),
where the DM was thermally produced in the early universe. Here, a new vector-like fermion …

In this work we study the hybrid kind of dark matter (DM) production mechanism where both
thermal and non-thermal contribution at two different epochs set the DM relic abundance …

Discrepancies of the $\Lambda {\rm CDM} $ model with small-scale cosmological
observations and stringent constraints from direct search experiments cast doubts over …

It is important to understand the implications of current observational constraints and
potential signatures on the thermal history of dark matter. In this paper, we build the …

A bstract We examine the singlet-doublet fermionic dark matter model, where the non-
thermal production of the dark matter in light of a non-standard cosmology demands a …

In this paper, we put forward a connection between the self-interacting dark matter and the
Dirac nature of neutrinos. Our exploration involves a Z 4⊗ Z 4′ discrete symmetry, wherein …
