WIMPy Leptogenesis in extended Scotogenic Model
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We address the possibility of realizing successful leptogenesis from dark matter annihilations in the scotogenic model of neutrino masses to explain the same order of magnitude abu…
Unification of Scotogenic Model with Pati-Salam gauge symmetry
Arnab Dasgupta, Sin Kyu Kang, Oleg Popov
In this work we demonstrate how Scotogenic model can arise naturally from an grand unified theory. Our model also includes a low scale Pati-Salam $SU(4)_c\times SU(2)_L\tim…
Effective chemical potential in spontaneous baryogenesis
Arnab Dasgupta, Rajeev Kumar Jain, Raghavan Rangarajan
Models of spontaneous baryogenesis have an interaction term in the Lagrangian, where is the baryonic current and can be a pseudo-Nambu-Goldstone boso…
TeV Scale Leptogenesis via Dark Sector Scatterings
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We propose a novel scenario of generating lepton asymmetry via annihilation and coannihilation of dark sector particles including t-channel processes. In order to realistically imp…
A UV Complete Framework of Freeze-in Massive Particle Dark Matter
Anirban Biswas, Debasish Borah, Arnab Dasgupta
We propose a way to generate tiny couplings of freeze-in massive particle dark matter with the Standard Model particles dynamically by considering an extension of the electroweak g…
