Excited bound states and their role in dark matter production
Tobias Binder, Mathias Garny, Jan Heisig +2
We explore the impact of highly excited bound states on the evolution of number densities of new physics particles, specifically dark matter, in the early Universe. Focusing on dip…
A Global Analysis of Resonance-enhanced Light Scalar Dark Matter
Tobias Binder, Sreemanti Chakraborti, Shigeki Matsumoto +1
We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analy…
Saha equilibrium for metastable bound states and dark matter freeze-out
Tobias Binder, Anastasiia Filimonova, Kalliopi Petraki +1
The formation and decay of metastable bound states can significantly decrease the thermal-relic dark matter density, particularly for dark matter masses around and above the TeV sc…
Non-Abelian Electric Field Correlator at NLO for Dark Matter Relic Abundance and Quarkonium Transport
Tobias Binder, Kyohei Mukaida, Bruno Scheihing-Hitschfeld +1
We perform a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU() plasma, which encodes properties of the plasma relevant for heav…
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…
Reannihilation of self-interacting dark matter
Tobias Binder, Michael Gustafsson, Ayuki Kamada +2
We explore the phenomenology of having a second epoch of dark matter annihilation into dark radiation long after the standard thermal freeze-out. Such a hidden reannihilation proce…
Early kinetic decoupling of dark matter: when the standard way of calculating the thermal relic density fails
Tobias Binder, Torsten Bringmann, Michael Gustafsson +1
Calculating the abundance of thermally produced dark matter particles has become a standard procedure, with sophisticated methods guaranteeing a precision that matches the percent-…
Matter Power Spectrum in Hidden Neutrino Interacting Dark Matter Models: A Closer Look at the Collision Term
Tobias Binder, Laura Covi, Ayuki Kamada +3
Dark Matter (DM) models providing possible alternative solutions to the small- scale crisis of standard cosmology are nowadays of growing interest. We consider DM interacting with…
