Title: Pushing the Limits of Dark Matter: New Approaches and Advanced Methods
Abstract
One of the biggest puzzles of astroparticle physics concerns the existence of dark matter (DM). Cosmological data indicates that DM represents around 25% of today's energy content of the Universe, while its nature has not been revealed yet. This talk will focus on DM candidates beyond the standard WIMP paradigm, in particular feebly interacting massive particles (FIMPs). I will highlight new approaches to probe FIMPs embedded in a consistent thermal history after inflation by combining results from collider experiments and cosmological data from PLANCK. At the same time, I will emphasize the importance of including effects of the hot thermal plasma of the early Universe in our theoretical predictions in order to obtain reliable results and hence a correct interpretation of experimental data.
