WIMPy Leptogenesis in extended Scotogenic Model
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We address the possibility of realizing successful leptogenesis from dark matter annihilations in the scotogenic model of neutrino masses to explain the same order of magnitude abu…
Compatibility of Flavour Symmetric Minimal Extended Seesaw with Neutrino Data
Neelakshi Sarma, Kalpana Bora, Debasish Borah
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 mi…
Right-handed Neutrino Dark Matter with Radiative Neutrino Mass in Gauged Model
Debasish Borah, Dibyendu Nanda, Nimmala Narendra +1
We study the possibility of right-handed neutrino dark matter (DM) in gauged extension of the standard model augmented by an additional scalar doublet, bein…
TeV scale leptogenesis, inflaton dark matter and neutrino mass in a scotogenic model
Debasish Borah, P. S. Bhupal Dev, Abhass Kumar
We consider the scotogenic model, where the standard model (SM) is extended by a scalar doublet and three odd SM-singlet fermions (, ), all odd under an additio…
keV Neutrino Dark Matter in a Fast Expanding Universe
Anirban Biswas, Debasish Borah, Dibyendu Nanda
We study the possibility of keV neutrino dark matter in the minimal gauge extension of the standard model where three right handed neutrinos are automatically included…
Correlating the anomalous results in decays with inert Higgs doublet dark matter and muon
Basabendu Barman, Debasish Borah, Lopamudra Mukherjee +1
In this article, we have considered an extension of the inert Higgs doublet model with singlet vector like fermions. Our model is capable of addressing some interesting a…
Linear Seesaw for Dirac Neutrinos with Flavour Symmetry
Debasish Borah, Biswajit Karmakar
We propose a linear seesaw model to realise light Dirac neutrinos within the framework of discrete flavour symmetry. The additional fields and their transformations under the…
TeV Scale Leptogenesis via Dark Sector Scatterings
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We propose a novel scenario of generating lepton asymmetry via annihilation and coannihilation of dark sector particles including t-channel processes. In order to realistically imp…
When Freeze-out Precedes Freeze-in: Sub-TeV Fermion Triplet Dark Matter with Radiative Neutrino Mass
Anirban Biswas, Debasish Borah, Dibyendu Nanda
We propose a minimal predictive scenario for dark matter and radiative neutrino mass where the relic abundance of dark matter is generated from a hybrid setup comprising of both th…
Common Origin of Dirac Neutrino Mass and Freeze-in Massive Particle Dark Matter
Debasish Borah, Biswajit Karmakar, Dibyendu Nanda
Motivated by the fact that the origin of tiny Dirac neutrino masses via the standard model Higgs field and non-thermal dark matter populating the Universe via freeze-in mechanism r…
Investigating the scalar sector of left-right symmetric models with leptonic probes
Debasish Borah, Benjamin Fuks, Deepanjali Goswami +1
We investigate the potential collider signatures of singly-charged and doubly-charged Higgs bosons such as those arising in minimal left-right symmetric models. Focusing on multile…
A UV Complete Framework of Freeze-in Massive Particle Dark Matter
Anirban Biswas, Debasish Borah, Arnab Dasgupta
We propose a way to generate tiny couplings of freeze-in massive particle dark matter with the Standard Model particles dynamically by considering an extension of the electroweak g…
