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…
The Influence of Lepton Portal on the WIMP-pFIMP framework
Jayita Lahiri, Dipankar Pradhan, Abhik Sarkar
The dynamics and detection possibility of a pseudo-FIMP (pFIMP) dark matter (DM) in the presence of a thermal DM have been studied in different contexts. The pFIMP phenomenology la…
Lepton collider as a window to reheating via freezing in dark matter detection. Part II
Basabendu Barman, Subhaditya Bhattacharya, Sahabub Jahedi +2
Dark matter (DM) genesis via Ultraviolet (UV) freeze-in embeds the seed of reheating temperature and dynamics in its relic density. Thus, discovery of such a DM candidate can possi…
Multiparticle scalar dark matter with symmetry
Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan
More than one dark sector particle transforming under the same symmetry provides one stable dark matter (DM) component which undergoes co-annihilation with the heavier particle(s)…
Lepton collider as a window to reheating via freezing in dark matter detection. Part I
Basabendu Barman, Subhaditya Bhattacharya, Sahabub Jahedi +2
We propose a methodology to infer the reheat temperature () of the Universe from the collider signal of freezing in dark matter (DM). We demonstrate it for the mono-…
