Theory Seminar (High Energy/Cosmology)
Oscillations and Baryogenesis
Date: Tuesday, February 2nd
Time: 3:30 pm
Place: 5280 Chamberlin Hall
Speaker: David McKeen, University of Washington
Abstract: In the context of inflationary cosmology, the matter-antimatter asymmetry of the Universe is a mystery. Dynamical explanations of this asymmetry are generally called baryogenesis. I will describe a new mechanism for baryogenesis at low temperatures, i.e. below the QCD confinement temperature, involving the (CP-violating) oscillation of states made of strongly interacting particles. In the course of this talk, I will also make connections to neutron-antineutron oscillations, clearing up issues that exist in the literature and pointing the way to novel experimental tests.
