Self Interacting Dark Matter and Dirac neutrinos via Lepton Quarticity
Satyabrata Mahapatra, Sujit Kumar Sahoo, Narendra Sahu +1
In this paper, we put forward a connection between the self-interacting dark matter and the Dirac nature of neutrinos. Our exploration involves a discrete symmet…
Phenomenology of the flavor symmetric scoto-seesaw model with dark matter and TM mixing
Joy Ganguly, Janusz Gluza, Biswajit Karmakar +1
We propose a hybrid scoto-seesaw model based on the non-Abelian discrete flavor symmetry. Light neutrino masses come from the tree-level type-I seesaw mechanism and from the…
Scotogenic origin of , W-mass anomaly and 95 GeV excess
Debasish Borah, Satyabrata Mahapatra, Partha Kumar Paul +1
We study a scotogenic extension of the minimal gauged model, including three right-handed singlet fermions and a scalar doublet all odd under an in-built symmetry t…
Singlet-doublet fermion dark matter with Dirac neutrino mass, and
Debasish Borah, Satyabrata Mahapatra, Dibyendu Nanda +2
We study the possibility of generating light Dirac neutrino mass via scotogenic mechanism where singlet-doublet fermion dark matter (DM) plays non-trivial role in generating one-lo…
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…
