Abstract
Dark matter particles' production, freeze-out, and relic abundance were examined and modeled. We found a solution for the Boltzmann equation, known as the Ricatti equation, for a dark matter particle. Using Mathematica, we numerically solved the differential Ricatti equation for several constant lambda values and created plots with the results. We solved for the dark matter density present today for several particle masses, and then related them to the freeze-out relic abundance of dark matter.
