Title: A journey through the jungle of thermal dark matter models
Abstract: To account for the evidence that 26% of the Universe is made up of dark matter, several general explanations have been proposed. The simplest mechanism relies on the existence of a new stable particle that would have been in thermal equilibrium with the Standard Model primordial plasma shortly after the Big Bang, and would have subsequently decoupled from it in a Boltzmann suppressed manner. There are many possible thermal dark matter models of this kind. One way to distinguish them is by how they account for its stability on cosmological time scales. This seminar is a journey through thermal dark matter models and their stabilization mechanisms. It is often said that recent experimental results have cast thermal dark matter models into crisis. This journey will also address this question.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
