Leptogenesis from a resonance
E. J. Chun, Arnab Dasgupta, Sin Kyu Kang
We propose a novel mechanism to realize leptogenesis through the Breit-Wigner resonance of a dark gauge boson , which mediates lepton number violating annihilations o…
Observing Left-Right Symmetry in the Cosmic Microwave Background
Debasish Borah, Arnab Dasgupta, Chayan Majumdar +1
We consider the possibility of probing left-right symmetric model (LRSM) via cosmic microwave background (CMB). We adopt the minimal LRSM with Higgs doublets, also known as the dou…
Observable Gravitational Waves in Minimal Scotogenic Model
Debasish Borah, Arnab Dasgupta, Kohei Fujikura +2
We scrutinise the widely studied minimal scotogenic model of dark matter (DM) and radiative neutrino mass from the requirement of a strong first order electroweak phase transition…
A new mechanism for matter-antimatter asymmetry and connection with dark matter
Arnab Dasgupta, P. S. Bhupal Dev, Sin Kyu Kang +1
We propose a new mechanism for generating matter-antimatter asymmetry via the interference of tree-level diagrams only, where the imaginary part of the Breit-Wigner propagator for…
Connecting ANITA Anomalous Events to a Non-thermal Dark Matter Scenario
Debasish Borah, Arnab Dasgupta, Ujjal Kumar Dey +1
The ANtarctic Impulsive Transient Antenna (ANITA) collaboration has observed two EeV-energy, upward going events originating from below the horizon. As no standard model (SM) parti…
Radiative Dirac Neutrino Mass with Dark Matter and it's implication to in the extension of the Standard Model
Arnab Dasgupta, Sin Kyu Kang, Oleg Popov
The Standard Model gauge symmetry is extended by which when spontaneously broken leads to residual symmetry. gauge symmetry made anomaly fr…
