Anatomy of RHN DM relic in the vanilla scotogenic neutrino mass model
Sujit Kumar Sahoo, Narendra Sahu, Vicky Singh Thounaojam
The scotogeneic neutrino mass models are very popular choices to generate light neutrino masses via radiative mechanism. In these models, the particles running in the loop are dist…

Light thermal dark matter models in the light of DAMIC-M 2025 constraints
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu +1
We study the viability of light thermal dark matter (DM) in sub-GeV mass range in view of the stringent new DAMIC-M limits on DM-electron scattering. Considering a Dirac fermion si…

Self-interacting dark matter with observable
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu +1
We propose a GeV-scale self-interacting dark matter (SIDM) candidate within a dark gauged extension of the Standard Model (SM), addressing small-scale structure issues in…
