Abstract

We show (1) that the two-body cross section for monopole-antimonopole annihilation is smaller when photon discreteness effects are included than previously believed; (2) that the three-body annihilation process should dominate the two-body process; but (3) that, even when monopole clumping and monopole dilution by entropy production is taken into account, these processes do not appear to provide a solution to the cosmological monopole problem in that either the monopoles do not annihilate or they annihilate so late that an unacceptable amount of entropy is produced.
