Fredagskollokvium, Yashar Akrami: Supersymmetric models of dark matter: constraints from cosmology and astroparticle physics

Weak-scale supersymmetry (SUSY) is one of the most favoured theories beyond the Standard Model (SM) of particle physics that elegantly solves several theoretical and observational problems in both particle physics and cosmology. SUSY is interesting for cosmologists particularly because it provides a viable and highly popular dark matter (DM) candidate. In this talk, I will briefly explain why we need DM and why we want to go beyond the SM. After a short description of theoretical foundations of SUSY and different issues that it can address, I will review some concrete SUSY models that are widely used in phenomenological studies. Various observational constraints on SUSY models from collider physics, astroparticle physics and cosmology will be discussed and some statistical frameworks and techniques for analyzing SUSY will be described.
