Note on the thermal history of decoupled massive particles
arXiv:0808.1552 · doi:10.1088/0264-9381/25/20/208001
Abstract
This note provides an alternative approach to the momentum decay and thermal evolution of decoupled massive particles. Although the ingredients in our results have been addressed in Ref.\cite{Weinberg}, the strategies employed here are simpler, and the results obtained here are more general.
