Cosmology

departure of a particle species from thermal equilibrium when its annihilation rate falls below the expansion rate, fixing its relic abundance.

In cosmology, thermal freeze-out refers to departure of a particle species from thermal equilibrium when its annihilation rate falls below the expansion rate, fixing its relic abundance. This meaning comes from Scherrer (1986) in Physical Review D.[1]
