A Predictive Model
George Lazarides, Rinku Maji, Rishav Roshan +1
We discuss some testable predictions of a non-supersymmetric model supplemented by a Peccei-Quinn symmetry. We utilize a symmetry breaking pattern of that yields…
Non-thermal leptogenesis and UV freeze-in of dark matter: impact of inflationary reheating
Basabendu Barman, Debasish Borah, Rishav Roshan
We study a minimal scenario to realize non-thermal leptogenesis and UV freeze-in of a Standard Model (SM) gauge singlet fermionic dark matter (DM) simultaneously, with inflaton fie…
Neutrino mass and asymmetric dark matter: study with inert Higgs doublet and high scale validity
Amit Dutta Banik, Rishav Roshan, Arunansu Sil
We consider an inert Higgs doublet (IHD) extension of the Standard Model accompanied with three right handed neutrinos and a dark sector, consisting of a singlet fermion and a scal…
Two Component Singlet-Triplet Scalar Dark Matter and Electroweak Vacuum Stability
Amit Dutta Banik, Rishav Roshan, Arunansu Sil
We propose a two component dark matter set-up by extending the Standard Model with a singlet and a hypercharge-less triplet scalars, each of them being odd under different sy…
Sub-TeV Singlet Scalar Dark Matter and Electroweak Vacuum Stability with Vector Like Fermions
Debasish Borah, Rishav Roshan, Arunansu Sil
We study a scalar singlet dark matter (DM) having mass in sub-TeV regime by extending the minimal scalar singlet DM setup by additional vector like fermions. While the minimal scal…
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…
