Description
We present a novel paradigm of dark matter freeze-out in the early universe, named "catalyzed freeze-out", in which the freeze-out of dark matter is controlled by catalyzed reactions. We discuss in detail the regime that the depletion of dark matter proceeds via $2\chi \to 2A'$ and $3A' \to 2\chi$ processes, in which $\chi$ and $A'$ denote dark matter and the catalyst respectively.
