Connecting Light Dirac Neutrinos to a Multi-component Dark Matter Scenario in Gauged Model
Dibyendu Nanda, Debasish Borah
We propose a new gauged extension of the standard model where light neutrinos are of Dirac type, naturally acquiring sub-eV mass after electroweak symmetry breaking, without…
Type III Seesaw for Neutrino Masses in Model with Multi-component Dark Matter
Anirban Biswas, Debasish Borah, Dibyendu Nanda
We propose a gauged extension of the Standard Model where light neutrino masses arise from type III seesaw mechanism. Unlike the minimal model with three right handed n…
Flavoured gauge extension of singlet-doublet fermionic dark matter: neutrino mass, high scale validity and collider signatures
Basabendu Barman, Debasish Borah, Purusottam Ghosh +1
We propose an Abelian gauged version of the singlet-doublet fermionic dark matter (DM) model where DM, combination of a vector like fermion doublet and a fermion singlet, is natura…
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…
Fermion Dark Matter with Leptogenesis in Minimal Scotogenic Model
Devabrat Mahanta, Debasish Borah
We study the possibility of singlet fermion dark matter (DM) and successful leptogenesis in minimal scotogenic model which also provides a common origin of DM and light neutrino ma…
Planck Scale Origin of Non-zero and Super-WIMP Dark Matter
Debasish Borah, Biswajit Karmakar, Dibyendu Nanda
We study a discrete flavour symmetric scenario for neutrino mass and dark matter under the circumstances where such global discrete symmetries can be explicitly broken at Planck sc…
Phenomenological Study of Texture Zeros in Lepton Mass Matrices of Minimal Left-Right Symmetric Model
Happy Borgohain, Mrinal Kumar Das, Debasish Borah
We consider the possibility of texture zeros in lepton mass matrices of the minimal left-right symmetric model (LRSM) where light neutrino mass arises from a combination of type I…
Common origin of modified chaotic inflation, non thermal dark matter and Dirac neutrino mass
Debasish Borah, Dibyendu Nanda, Abhijit Kumar Saha
We propose a minimal extension of the standard model of particle physics to accommodate cosmic inflation, dark matter and light neutrino masses. While the inflationary phase is obt…
Minimal Two-component Scalar Doublet Dark Matter with Radiative Neutrino Mass
Debasish Borah, Rishav Roshan, Arunansu Sil
We propose a minimal extension of the Standard Model to accommodate two-component dark matter (DM) and light neutrino mass. The symmetry of the Standard Model is enhanced by an unb…
Two-component Dark Matter with co-genesis of Baryon Asymmetry of the Universe
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We discuss the possibility of realising a two-component dark matter (DM) scenario where the two DM candidates differ from each other by virtue of their production mechanism in the…
