Implications of NANOGrav results and UV freeze-in in a fast-expanding Universe
Basabendu Barman, Amit Dutta Banik, Avik Paul
Recent pulsar timing data reported by the NANOGrav collaboration indicates the existence of a stochastic gravitational wave (GW) background at a frequency . W…
Feebly coupled vector boson dark matter in effective theory
Basabendu Barman, Subhaditya Bhattacharya, Bohdan Grzadkowski
A model of dark matter (DM) that communicates with the Standard Model (SM) exclusively through suppressed dimension five operator is discussed. The SM is augmented with a symmetry…
Effective Theory of Freeze-in Dark Matter
Basabendu Barman, Debasish Borah, Rishav Roshan
We perform a model independent study of freeze-in of massive particle dark matter (DM) by adopting an effective field theory framework. Considering the dark matter to be a gauge si…
