A Common Origin of Asymmetric Self-interacting Dark Matter and Dirac Leptogenesis
Manoranjan Dutta, Nimmala Narendra
Assuming dark matter to be asymmetric as well as self-interacting and neutrinos to be Dirac fermions, we propose a framework to address the observed baryon imbalance of the univers…
Self-interacting Dark Matter in Non-Standard Cosmology
Manoranjan Dutta
Discrepancies of the model with small-scale cosmological observations and stringent constraints from direct search experiments cast doubts over typical weak scale cold…
Asymmetric Self-interacting Dark Matter via Dirac Leptogenesis
Manoranjan Dutta, Nimmala Narendra, Narendra Sahu +1
The nature of neutrinos, whether Dirac or Majorana, is hitherto not known. Assuming that the neutrinos are Dirac, which needs to be an exact symmetry, we make an attempt to e…
Singlet-Doublet Self-interacting Dark Matter and Radiative Neutrino Mass
Debasish Borah, Manoranjan Dutta, Satyabrata Mahapatra +1
Self-interacting dark matter (SIDM) with a light mediator is a promising scenario to alleviate the small-scale problems of the cold dark matter paradigm while being consistent with…
Self-interacting Dark Matter via Right Handed Neutrino Portal
Debasish Borah, Manoranjan Dutta, Satyabrata Mahapatra +1
We propose a self-interacting dark matter (DM) scenario with right handed neutrino (RHN) portal to the standard model (SM). The dark sector consists of a particle DM, assumed to be…
Lepton Anomalous Magnetic Moment with Singlet-Doublet Fermion Dark Matter in Scotogenic Model
Debasish Borah, Manoranjan Dutta, Satyabrata Mahapatra +1
We study an extension of the minimal gauged model in order to explain the anomalous magnetic moments of muon and electron simultaneously. Presence of an additional scalar…
Boosted Self-Interacting Dark Matter and XENON1T Excess
Debasish Borah, Manoranjan Dutta, Satyabrata Mahapatra +1
We present a self-interacting boosted dark matter (DM) scenario as a possible explanation of the recently reported excess of electron recoil events by the XENON1T experiment. The S…
Majorana Dark Matter and Neutrino mass in a singlet-doublet extension of the Standard Model
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
A minimal extension of the Standard Model (SM) by a vector-like fermion doublet and three right handed (RH) singlet neutrinos is proposed in order to explain dark matter and tiny n…
Muon and XENON1T Excess with Boosted Dark Matter in Model
Debasish Borah, Manoranjan Dutta, Satyabrata Mahapatra +1
Motivated by the growing evidence for lepton flavour universality violation after the first results from Fermilab's muon measurement, we revisit one of the most widely stud…
Self-interacting Inelastic Dark Matter in the light of XENON1T excess
Manoranjan Dutta, Satyabrata Mahapatra, Debasish Borah +1
We propose a self-interacting inelastic dark matter (DM) scenario as a possible origin of the recently reported excess of electron recoil events by the XENON1T experiment. Two quas…
Singlet-Doublet Majorana Dark Matter and Neutrino Mass in a minimal Type-I Seesaw Scenario
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
In a bid to simultaneous explanation of dark matter (DM) and tiny but non-zero masses of left-handed neutrinos, we propose a minimal extension of the Standard Model (SM) by a vecto…
