Description

Title : Langevin simulation of dark matter kinetic equilibrium

Speaker : Prof. M. Laine (AEC, U. Bern, Switzerland)

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.
