#12 How did dark matter freeze in the early universe?

There are several ways to arrive at the amount of dark matter we observe today. Two of the most popular mechanisms are the "freeze-out" and the "freeze-in" mechanisms. Although both are in the mass region of the so-called WIMPS (Weekly Interacting Massive Particles), the region for the values of the gate coupling between dark matter and visible matter is many orders of magnitude away. This project aims to start from one of the simplest models that admits the existence of dark matter, the extension of the Standard Model by a singleto, and compare the regions where each of the mechanisms is the dominant one.
