TeV scale leptogenesis, inflaton dark matter, and neutrino mass in a scotogenic model
/ Borah, Debasish ; Dev, P. S. Bhupal ; Kumar, Abhass
We consider the scotogenic model, where the standard model (SM) is extended by a scalar doublet and three ${Z}_{2}$ odd SMsinglet fermions (${N}_{i}$, $i=1$, 2, 3), all odd under an additional ${Z}_{2}$ symmetry, as a unifying framework for simultaneous explanation of inflation, dark matter, baryogenesis and neutrino mass.

Compatibility of A4 flavour symmetric minimal extended seesaw with (3+1) neutrino data
/ Sarma, Neelakshi ; Bora, Kalpana ; Borah, Debasish
Motivated by the recent resurrection of the evidence for an eV scale sterile neutrino from the MiniBooNE experiment, we revisit one of the most minimal seesaw model known as the minimal extended seesaw that gives rise to a 3+1 light neutrino mass matrix. [...]

UV complete framework of freezein massive particle dark matter
/ Biswas, Anirban ; Borah, Debasish ; Dasgupta, Arnab
We propose a way to generate tiny couplings of freezein massive particle dark matter with the standard model particles dynamically by considering an extension of the electroweak gauge symmetry. [...]

keV neutrino dark matter in a fast expanding universe
/ Biswas, Anirban ; Borah, Debasish ; Nanda, Dibyendu
We study the possibility of keV neutrino dark matter in the minimal U(1)B−L gauge extension of the standard model where three right handed neutrinos are automatically included due to the requirement of anomaly cancellations. [...]

A 4 flavour model for Dirac neutrinos: Type I and inverse seesaw

Multicomponent fermionic dark matter and IceCube PeV scale neutrinos in leftright model with gauge unification
/ Borah, Debasish ; Dasgupta, Arnab ; Dey, Ujjal ; Patra, Sudhanwa ; et al
We consider a simple extension of the minimal leftright symmetric model (LRSM) in order to explain the PeV neutrino events seen at the IceCube experiment from a heavy decaying dark matter. [...]

Lepton portal limit of inert Higgs doublet dark matter with radiative neutrino mass
/ Borah, Debasish ; Sadhukhan, Soumya ; Sahoo, Shibananda
We study an extension of the Inert Higgs Doublet Model (IHDM) by three copies of right handed neutrinos and heavy charged leptons such that both the inert Higgs doublet and the heavy fermions are odd under the Z2 symmetry of the model. [...]
