Baryon-dark matter coincidence in Randall-Sundrum Model
Basabendu Barman, Ashmita Das, Partha Kumar Paul +2
Within the framework of the extra-dimensional Randall-Sundrum set-up, we investigate the freeze-in production of Standard Model (SM) gauge-singlet scalar, fermionic, and massive ve…

Freeze-in production of scalaron dark matter in gravity
Basabendu Barman, Ashmita Das, Rakesh Kumar SivaKumar +1
We demonstrate that the scalaron, a scalar degree of freedom, emerging from the theory of gravity, can account for the observed dark matter (DM) abundance if its mass is aro…
