Perturbative Unitarity Violation in Radiative Capture Transitions to Dark Matter Bound States
Martin Beneke, Tobias Binder, Lorenzo de Ros +2
We investigate the formation of bound states of non-relativistic dark matter particles subject to long-range interactions through radiative capture. The initial scattering and fina…

Enhancement of -wave dark matter annihilation by quasi-bound states
Martin Beneke, Tobias Binder, Lorenzo De Ros +1
We scrutinize the Sommerfeld enhancement in dark matter pair annihilation for -wave and higher- partial waves. For the Yukawa potential these feature a super-resonant Brei…
