Dark Matter Sommerfeld-enhanced annihilation and Bound-state decay at finite temperature
Tobias Binder, Laura Covi, Kyohei Mukaida
Traditional computations of the dark matter (DM) relic abundance, for models where attractive self-interactions are mediated by light force-carriers and bound states exist, rely on…

Dark Matter Relic Density Revisited: The Case For Early Kinetic Decoupling
Tobias Binder, Torsten Bringmann, Michael Gustafsson +1
Kinetic decoupling of dark matter typically happens much later than chemical freeze-out. In fact, local thermal equilibrium is an important assumption for the usual relic density c…
