Title: Hot Universe and Dark Matter
Time: 14:00 CDT
Abstract: In this seminar we will focus on the different thermal stages that follow the inflationary phase of the Universe. We will insist in detail on the process of reheating, and the evolution of the temperature at the early moments, insisting particularly on the non-instantaneous effects. Finally, we will show why the knowledge of thermalization is indeed necessary for the study of dark matter production.
