Connection between dark matter abundance and primordial tensor perturbations
P. S. Bhupal Dev, Anupam Mazumdar, Saleh Qutub
Primordial inflation and Dark Matter (DM) could both belong to the hidden sector. It is therefore plausible that the inflaton, which drives inflation, could couple to the DM either…
A Possible Two-component Flux for the High Energy Neutrino Events at IceCube
Chien-Yi Chen, P. S. Bhupal Dev, Amarjit Soni
Understanding the spectral and flavor composition of the astrophysical neutrino flux responsible for the recently observed ultra-high energy events at IceCube is of great importanc…
Kadanoff-Baym Approach to Flavour Mixing and Oscillations in Resonant Leptogenesis
P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis +1
We describe a loopwise perturbative truncation scheme for quantum transport equations in the Kadanoff-Baym formalism, which does not necessitate the use of the so-called Kadanoff-B…
Flavour Covariant Formalism for Resonant Leptogenesis
P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis +1
We present a fully flavour-covariant formalism for transport phenomena and apply it to study the flavour-dynamics of Resonant Leptogenesis (RL). We show that this formalism provide…
Maximally Symmetric Two Higgs Doublet Model with Natural Standard Model Alignment
P. S. Bhupal Dev, Apostolos Pilaftsis
We study the Higgs mass spectrum as predicted by a Maximally Symmetric Two Higgs Doublet Model (MS-2HDM) potential based on the SO(5) group, softly broken by bilinear Higgs mass te…
Leptogenesis Constraints on the Mass of Right-handed Gauge Bosons
P. S. Bhupal Dev, Chang-Hun Lee, R. N. Mohapatra
We discuss leptogenesis constraints on the mass of the right-handed -boson () in a TeV-scale Left-Right seesaw model (LRSM) for neutrino masses. For generic Dirac mass of t…
