Particle Theory Seminar | Yue Zhang (Carleton U.) – “New Prospects of Sterile Neutrino Dark Matter”

Seminar Organizer

Event Details

Sterile neutrino is a very simple dark matter candidate. In the minimal incarnation, the original Dodelson-Widrow mechanism that explains its relic abundance is in strong tension with indirect detection constraints. I present the self interacting neutrino scenario, mediated by a Majoron-like scalar or vector boson, as a novel solution to the above tension. It opens up new & wide parameter space for sterile neutrino dark matter, and results in a number of testable signatures from the laboratories to the cosmos.
