Center-of-mass recoil effects on the annihilation and formation of dark matter bound pairs
Simone Biondini, Nora Brambilla, Gramos Qerimi +1
For a quantitative investigation on the time evolution of heavy thermal dark matter at and after thermal freeze-out, near-threshold processes need to be taken into account which ha…

Effective field theories for dark matter pairs in the early universe: center-of-mass recoil effects
Simone Biondini, Nora Brambilla, Gramos Qerimi +1
For non-relativistic thermal dark matter, close-to-threshold effects largely dominate the evolution of the number density for most of the times after thermal freeze-out, and hence…
