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…
Verifiable type-III seesaw and dark matter in a gauged symmetric model
Satyabrata Mahapatra, Partha Kumar Paul, Narendra Sahu +1
We propose a new extension of the Standard Model that incorporates a gauged \( U(1)_{\rm B-L} \) symmetry and the type-III seesaw mechanism to explain neutrino mass generation and…
Effective theory of light Dirac neutrino portal dark matter with observable
Debasish Borah, Satyabrata Mahapatra, Dibyendu Nanda +2
We study the possibility of light Dirac neutrino portal dark matter (DM) in an effective field theory setup. Dirac nature of light neutrino automatically includes its right chiral…
