MLL-Kolloquium: Dr. Bhupal Dev (TUM/T30d und MPI f. Kernphysik, Heidelberg): A Testable Mechanism for Baryogenesis

Thursday 17 Dec 2015, 16:00 → 17:00 Europe/Berlin

Seminarraum 127, Erdgeschoss/Nord (TUM Physik II)

The observed baryon-asymmetry in our Universe is one of the major evidences for new physics beyond the Standard Model. I will review some popular baryogenesis mechanisms for dynamically generating this asymmetry, with a particular emphasis on their testability in future experiments. Then I will discuss a simple model for baryon and lepton number violation, where the stability of the proton is connected to the smallness of the neutrino masses. Matter-antimatter asymmetry in this model can be generated at either above or below the electroweak scale, independent of the sphaleron processes. Possible collider signatures and other low-energy probes will also be discussed.
