A study of potential non-relativistic QED pairs in the Keldysh-Schwinger formalism
Tobias Binder
Potential non-relativistic Quantum Electrodynamics and the Keldysh-Schwinger formalism is used to derive Kadanoff-Baym-like equations for two-body field correlators. These cover th…
DRAKE: Dark matter Relic Abundance beyond Kinetic Equilibrium
Tobias Binder, Torsten Bringmann, Michael Gustafsson +1
We introduce DRAKE, a numerical precision tool for predicting the dark matter relic abundance also in situations where the standard assumption of kinetic equilibrium during the fre…
Dark Matter bound-state formation at higher order: a non-equilibrium quantum field theory approach
Tobias Binder, Burkhard Blobel, Julia Harz +1
The formation of meta-stable dark matter bound states in coannihilating scenarios could efficiently occur through the scattering with a variety of Standard Model bath particles, wh…
Rapid bound-state formation of Dark Matter in the Early Universe
Tobias Binder, Kyohei Mukaida, Kalliopi Petraki
The thermal decoupling description of dark matter (DM) and co-annihilating partners is reconsidered. If DM is realized at around the TeV-mass region or above, even the heaviest ele…
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…
