- TITLE
- Langevin simulation of dark matter kinetic equilibration
- ABSTRACT
- Dark matter computations based on the freeze-out mechanism regularly
assume the presence of kinetic equilibrium, however recently the validity
of this assumption has been questioned in specific cases. We show how
kinetic equilibration can be studied numerically, with the help of
Langevin simulations. A benchmark point is taken from the scalar singlet
model in the resonant regime (scalar mass 60 GeV). For fixed couplings,
effects on the 40% level can be found for the final abundance.
