Hot Yang-Mills Theory and The Center Symmetry
Speaker:Aleksi Kurkela (University of Helsinki)
Abstract:I will review the construction of dimensionally reduced high-temperature effective theories for SU(2) and SU(3) Yang-Mills theory that preserve the Z(N_c) center symmetry of the original theory and are expected to be valid on a wider temperature range than the usual effective theory EQCD. I will also present results from recent numerical simulations, and based on them, will sketch the structure of the phase diagrams of the effective theories.

Gravitino Dark Matter and Big Bang Nucleosynthesis
Speaker:Prof. Vassilis Spanos (University of Patras, Greece)
Abstract:We will discuss the possibility that the Dark Matter particle is the gravitino, the super¬symmetric partner of graviton. In this case, the next-to-lightest super¬symmetric particle (NLSP), is either the stau, the partner of the tau lepton, or the neutralino. The NLSP is long lived and decays gravitationaly during or after the Big Bang Nucleosynthesis (BBN) era. Hence, this scenario is severely constrained by the BBN predictions for the light elements abundance. Moreover, if the NLSP is the negatively charged stau, bound states can be formed with the light elements.
