arXiv:1601.00817 · doi:10.1088/1742-6596/718/4/042059
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.
