Improved Numerical Analysis of Thermal WIMP model of Dark Matter

Authors: Subhayan Sahu

This report contains a short review of the thermal WIMP model of Dark matter, followed by an improved numerical analysis that takes into account the evolution of effective degrees of freedom for Standard Model particles to solve the evolution equation. The result dictates that for low-mass WIMPs, the cross section required to match the current Dark Matter relic density is significantly different from the oft-quoted value.
