Abundances from the Boltzmann Equation
Dark Matter, WIMPs, Boltzmann Equation, Relic Abundaces.
Observational data that support the existence of dark matter (DM) has been largely documented, pointing to the presence of a non-baryonic matter that is responsible for around 25% of the energy budget of the Universe. However, such type of matter has not been detected so far, and the standard model of particle physics (SM) does not have an explanation for DM. In this work, the weakly interacting massive particles (WIMPs), the main candidates for DM, are presented. It is then the main goal to show that this DM candidate generates the abundance required to obtain the estimated amount of DM in the Universe. This result is obtained by solving the Boltzmann equation, in the early Universe scenario.
