Two (more) exceptions in the calculations of relic abundances

Andrzej Hryczuk, FI

The thermal relic abundance of the dark matter is now determined observationally to a per cent level accuracy. It is also an increasingly useful tool to exclude, constrain or motivate models beyond the Standard Model of particle physics. It comes then with no surprise that in the recent years a considerable effort has been made to revise and improve some of the aspects of thermal relic density calculations. In this talk I will concentrate on the important physics concepts used in such calculations, highlighting some less commonly discussed details. Towards the end I will show some recent results, serving as examples of the relevance of the effects studied.
