Title: New effects in dark matter production
Abstract
How was dark matter produced in the early Universe? Answering this question is of great importance since it allows us to predict the expected experimental signatures. I will discuss non-perturbative effects in coannihilation driven freeze-out, i.e. Sommerfeld enhancement and bound state formation in a thermal environment, and analyze the connection with phenomenology. In addition, I will comment on the conditions for freeze-out and point out an alternative production mechanism of dark matter which relies on conversion processes instead of annhilations and predicts long-lived particles at the LHC.
