Self-consistent computation of pair production from non-relativistic effective field theories in the Keldysh-Schwinger formalism

Tobias Binder, Edward Wang

Sommerfeld-enhanced annihilation cross sections in the presence of nearly zero-energy bound states can become so large that perturbative partial-wave unitarity appears to be violat…

BSFfast: Rapid computation of bound-state effects on annihilation in the early Universe

Tobias Binder, Mathias Garny, Jan Heisig +1

Bound-state formation (BSF) can have a large impact on annihilation of new physics particles with long-range interactions in the early Universe. In particular, the inclusion of exc…

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…

Towards a precision calculation of in the Standard Model IV: Estimating the impact of positronium formation

Tobias Binder, Marco Drewes, Yannis Georis +3

We present a first assessment of how the previously unexplored effect of positronium formation can impact on the value of the effective number of neutrino species in the Standard M…

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…
