A Testable Mechanism for Baryogenesis
Dr. Bhupal Dev, Physik Department T30d/TUM und MPI f. Kernphysik, Heidelberg
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.
