Resumen
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.
