Multi-messenger FIMP
Debasish Borah, Nayan Das, Sahabub Jahedi +1
We propose a multi-messenger frontier probe of non-thermal or freeze-in massive particle (FIMP) dark matter (DM) by considering an effective field theory (EFT) setup. Assuming lept…
Direct Search signal of two-component Dark Matter
Subhaditya Bhattacharya, Dipankar Pradhan
How do we know if the dark sector consists of more than one dark matter (DM) component is an important question, for which the answer is not very definite. In this article we study…
Two-component Dark Matter and low scale Thermal Leptogenesis
Subhaditya Bhattacharya, Devabrat Mahanta, Niloy Mondal +1
The observable cosmos exhibits sizable baryon asymmetry, small active neutrino masses, and the presence of dark matter (DM). To address these phenomena together, we propose a two c…
Pseudo-FIMP dark matter in presence of a SIMP
Subhaditya Bhattacharya, Dipankar Pradhan, Jahaan Thakkar
Pseudo-feebly Interacting Massive Particle (pFIMP) has been postulated in two component dark matter (DM) scenarios, where it has feeble interaction with the visible sector, but siz…
