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…
