Streszczenie: 

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. Interestingly, this mechanism points towards long-lived particles at could be observed at the LHC.
