Kinetic decoupling of WIMPs: analytic expressions
arXiv:1501.02233 · doi:10.1103/PhysRevD.91.083526
Abstract
We present a general expression for the values of the average kinetic energy and of the temperature of kinetic decoupling of a WIMP, valid for any cosmological model. We show an example of the usage of our solution when the Hubble rate has a power-law dependence on temperature, and we show results for the specific cases of kination cosmology and low- temperature reheating cosmology.
