| Description: | [DPS Seminar] Dr. Aritra Gupta (Instituto de Física Corpuscular (IFIC), Valencia, Spain) -- Seesaw determination of the dark matter relic density |
| Date: | Wednesday, Apr 24, 2024 |
| Time: | 2 p.m. - 3:30 p.m. |
| Venue: | Asima Chatterjee Lecture Theatre |
| Details: | We show that in the usual type-I seesaw framework, augmented solely by a neutrino portal interaction, the dark matter relic density can be created through freeze-in, in a manner fully determined by the seesaw interactions and the DM particle mass. This simple freeze-in scenario, where dark matter is not in a seesaw state, proceeds through slow, seesaw-induced decays of Higgs W and Z bosons. We identify two scenarios, one of which predicts the existence of an observable neutrino line |
