Content
Several mechanisms generating relic abundance of ALP dark matter involve processes which take place before, during or after cosmic inflation. In such cases fundamental role is played by PQ field potential. We investigate radiative, thermal and geometric corrections to PQ field dynamics in scenarios in which the potential has very small self-coupling. We will focus on models with quasi-supersymmeric spectrum and discuss in what manner taking account of the corrections are crucial for estimating ALP DM relics.
