New constraints on from captured dark matter annihilation in astrophysical objects
Basabendu Barman, Pooja Bhattacharjee, Arindam Das
Considering dark matter capture in astrophysical objects such as neutron stars and brown dwarfs, followed by their annihilation into two neutrino and four neutrino final states, we…

What KM3-230213A events may tell us about the neutrino mass and dark matter
Basabendu Barman, Arindam Das, Prantik Sarmah
Within the framework of general scenario, we demonstrate that the ultra high energy neutrinos recently detected by KM3NeT could originate from a decaying right handed neutri…

Hunting for heavy with IceCube neutrinos and gravitational waves
Basabendu Barman, Arindam Das, Suruj Jyoti Das +1
In the minimal gauged B-L extension of the Standard Model, we demonstrate that PeV-scale dark matter (DM) and the baryon asymmetry of the Universe (BAU) can be simultaneously expla…
