Phenomenology of Dirac neutrino EFTs up to dimension six
Anirban Biswas, Eung Jin Chun, Sanjoy Mandal +1
The gauge-singlet right-handed neutrinos would be essential to explain the tiny masses of active neutrinos. We consider the effective field theory of the Standard Model extended wi…
Impact of Non-universal Z^' in the Lepton Flavour Violating B(B_s ) to K^* (ϕ) l_1^- l_2^+ decays
S. Biswas, S. Mahata, A. Biswas +1
In recent years, lepton flavour violating (LFV) decays are one of the most trending topics to probe new physics (NP). The latest results of LHCb have motivated us to study the LFV…
WIMPs in Dilatonic Einstein Gauss-Bonnet Cosmology
Anirban Biswas, Arpan Kar, Bum-Hoon Lee +5
We use the Weakly Interacting Massive Particle (WIMP) thermal decoupling scenario to probe Cosmologies in dilatonic Einstein Gauss-Bonnet (dEGB) gravity, where the Gauss-Bonnet ter…
Concealing Dirac neutrinos from cosmic microwave background
Anirban Biswas, Dilip Kumar Ghosh, Dibyendu Nanda
The existence of prolonged radiation domination prior to the Big Bang Nucleosynthesis (BBN), starting just after the inflationary epoch, is not yet established unanimously. If inst…
Improved White Dwarves Constraints on Inelastic Dark Matter and Left-Right Symmetric Models
Anirban Biswas, Arpan Kar, Hyomin Kim +2
WIMPs can be captured in compact stars such as white dwarves (WDs) leading to an increase in the star luminosity through their annihilation process. We show that when the WIMP inte…
Freeze-in Dark Matter via Light Dirac Neutrino Portal
Anirban Biswas, Debasish Borah, Nayan Das +1
We propose a scenario where dark matter (DM) can be generated non-thermally due to the presence of a light Dirac neutrino portal between the standard model (SM) and dark sector par…

Anirban Biswas, Sarif Khan
The quest for new physics beyond the Standard Model is boosted by the recently observed deviation in the anomalous magnetic moments of muon and electron from their respective theor…
Light Dirac neutrino portal dark matter with observable
Anirban Biswas, Debasish Borah, Dibyendu Nanda
We propose a Dirac neutrino portal dark matter scenario by minimally extending the particle content of the Standard Model (SM) with three right handed neutrinos (), a Dirac fe…
When Freeze-out occurs due to a non-Boltzmann suppression: A study of degenerate dark sector
Anirban Biswas, Sougata Ganguly, Sourov Roy
Exponential suppression or commonly known as the Boltzmann suppression in the number density of dark matter is the key ingredient for creating chemical imbalance prior to the usual…
Non-thermal production of lepton asymmetry and dark matter in minimal seesaw with right handed neutrino induced Higgs potential
Rome Samanta, Anirban Biswas, Sukannya Bhattacharya
Within Type-I seesaw mechanism, Higgs mass can be dynamically generated via quantum effects of the right handed neutrinos assuming the potential is nearly conformal at the Ultra-Vi…
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…
Reconciling dark matter, anomalies and in an scenario
Anirban Biswas, Avirup Shaw
We propose an anomaly free unified scenario by invocation of an extra local gauge symmetry. This scenario simultaneously resolves the anomalies…
Common origin of baryon asymmetry, dark matter and neutrino mass
Anirban Biswas, Sandhya Choubey, Laura Covi +1
In this work, we explain three beyond standard model (BSM) phenomena, namely neutrino masses, the baryon asymmetry of the Universe and Dark Matter, within a single model and in eac…

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…
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…
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…
Inverse seesaw and dark matter in a gauged extension with flavour symmetry
Anirban Biswas, Sandhya Choubey, Sarif Khan
We propose a model which generates neutrino masses by the inverse seesaw mechanism, provides a viable dark matter candidate and explains the muon () anomaly. The Standard Mode…
