Self-interacting dark matter and the GRB221009A event
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu +1
In this work, we explore the intriguing possibility of connecting self-interacting dark matter (SIDM) with the recently observed exceptionally bright and long-duration Gamma Ray Bu…
Asymmetric long-lived dark matter and leptogenesis from type-III seesaw framework
Satyabrata Mahapatra, Partha Kumar Paul, Narendra Sahu +1
We propose a simple model in the type-III seesaw framework to explain the neutrino mass, asymmetric dark matter (ADM), and baryon asymmetry of the Universe. We extend the standard…
Gauged symmetry, fourth generation, neutrino mass and dark matter
Satyabrata Mahapatra, Rabindra N. Mohapatra, Narendra Sahu
We present two models where the familiar leptonic symmetry is a gauge symmetry. We show how anomaly cancellation constrains the allowed theories, with one of them req…
A new realisation of light thermal self-interacting dark matter and detection prospects
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu
Light dark matter (DM) in the GeV ballpark faces weaker constraint from direct detection experiments. If such DM also has sufficient self-interactions due to a light mediator, it c…
Singlet-Doublet Fermion Origin of Dark Matter, Neutrino Mass and W-Mass Anomaly
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu
Motivated by the recently reported anomaly in W boson mass by the CDF collaboration with statistical significance, we consider a singlet-doublet (SD) Majorana fermion dark mat…
Type II Dirac Seesaw with Observable in the light of W-mass Anomaly
Debasish Borah, Satyabrata Mahapatra, Dibyendu Nanda +1
We propose a type II seesaw model for light Dirac neutrinos to provide an explanation for the recently reported anomaly in W boson mass by the CDF collaboration with statistic…
