Freeze-in and Freeze-out in a Right-Handed Neutrino Extended MSSM with a Seesaw Mechanism
Tushar Gupta, Matti Heikinheimo, Katri Huitu +1
We investigate the possibility of saturating the relic density bound with light Higgsinos. When the minimal supersymmetric Standard Model is extended with right-handed neutrino sup…

Boosted Dark Matter Driven by Cosmic Rays and Diffuse Supernova Neutrinos
Dilip Kumar Ghosh, Tushar Gupta, Matti Heikinheimo +2
Direct detection of light dark matter can be significantly enhanced by up-scattering of dark matter with energetic particles in the cosmic ambient. This boosted dark matter flux ca…
