Cogenesis of visible and dark matter in a scotogenic model
Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray
Within a scotogenic neutrino mass model we explore the cogenesis of matter from the CP violating decay of a heavy -odd right handed neutrino that simultaneously popul…

Complex Scalar Singlet Model: Electroweak Phase Transition and Gravitational Waves
Dilip Kumar Ghosh, Debadrita Mukherjee, Koustav Mukherjee +1
The Standard Model (SM) cannot explain the observed baryon asymmetry of the Universe (BAU), thus driving the need for physics beyond the SM, which can generate electroweak baryogen…

Neutrinos from captured dark matter in galactic stars
Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray
Sub-GeV neutrinos produced in a stellar core may emerge from main sequence stars, white dwarfs and brown dwarfs producing possible observable signals of dark matter capture. A dist…
