Analytic expressions for the kinetic decoupling of WIMPs [CEA]

http://arxiv.org/abs/1601.00817


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.
