Journal ArticleDOI
Rapid Bound State Formation of Dark Matter in the Early Universe
TL;DR: If the mediator is coupled in a direct way to any relativistic species present in the early Universe, it is demonstrated that BSF can much more efficiently occur through particle scattering.
Journal ArticleDOI
Dark matter bound-state formation at higher order: a non-equilibrium quantum field theory approach
TL;DR: In this paper, the authors derived the bound-state formation collision term in the framework of non-equilibrium quantum field theory and derived an expression for a more general cross section, which allows to compute higher-order bound state formation processes inside the primordial plasma background in a comprehensive manner.
Journal ArticleDOI
Dark matter relic abundance beyond kinetic equilibrium
TL;DR: Drake as mentioned in this paper is a numerical precision tool for predicting the dark matter relic abundance also in situations where the standard assumption of kinetic equilibrium during the freeze-out process may not be satisfied.

Non-Abelian Electric Field Correlator at NLO for Dark Matter Relic Abundance and Quarkonium Transport
Tobias Binder,Bruno Scheihing-Hitschfeld,Kyohei Mukaida,Bruno Scheihing-Hitschfeld,Xiaojun Yao +4 more
TL;DR: In this article, a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU$N_c$) plasma, which encodes properties of the plasma relevant for heavy particle bound state formation and dissociation, is carried out in the real-time formalism of thermal field theory.

Saha equilibrium for metastable bound states and dark matter freeze-out.
TL;DR: In this paper, a closed-form expression for the effective cross-section for an arbitrary number of bound states was derived, and it was shown that bound-to-bound transitions can only increase it.
