A simple model for magnetic inelastic dark matter (MiDM)
Sudhanwa Patra, Soumya Rao
A simple model for magnetic inelastic dark matter (MiDM), which is a minimal extension of the standard model with right-handed neutrinos (), a singly charged scalar () and…
Scalar Neutrino as Asymmetric Dark Matter: Radiative Neutrino Mass and Leptogenesis
Ernest Ma, Utpal Sarkar
In the Minimal Supersymmetric Standard Model (MSSM), the scalar neutrino has odd R parity, yet it has long been eliminated as a dark-matter candidate because it scatter…
Neutrino processes with power law dispersion relations
Subhendra Mohanty, Soumya Rao
We compute various processes involving neutrinos in the initial and/or final state and we assume that neutrinos have energy momentum relation with a general power law $E^2 =p^2+ ξ_…
Strong CP violation and chiral symmetry breaking in hot and dense quark matter
Bhaswar Chatterjee, Hiranmaya Mishra, Amruta Mishra
We investigate chiral symmetry breaking and strong CP violation effects in the phase diagram of strongly interacting matter. We demonstrate the effect of strong CP violating terms…
Generation of scale invariant density perturbations in a conformally invariant Inert Higgs doublet model
Moumita Das, Subhendra Mohanty
If a Higgs field is conformally coupled to gravity, then it can give rise to the scale invariant density perturbations. We make use of this result in a realistic inert Higgs double…
Spontaneous CP violation in quark scattering from QCD Z(3) interfaces
Abhishek Atreya, Anjishnu Sarkar, Ajit M. Srivastava
In this paper, we explore the possibility of spontaneous CP violation in the scattering of quarks and anti-quarks from QCD Z(3) domain walls. The CP violation here arises from the…
