Post freeze-out annihilations in the early universe
Abstract
We investigate the possible effect of the residual annihilations of heavy particles after freeze-out from equilibrium in the early universe. An error in previous work on this subject is pointed out and the correct method of solving the Boltzmann equation for this case is developed. For Majorana particles there are significant differences relative to previous work.
