A Unitary Fixed Point Away from Threshold: Momentum-Surface EFT for Strong Mixing
Lorenzo De Ros, Javier Reig Navarro
Radiative capture in a non-relativistic system can become non-perturbative even when the underlying transition interaction is weak. We demonstrate this mechanism in a simple quantu…

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…
