Pair production of black holes on cosmic strings

Abstract

We discuss the pair creation of black holes by the breaking of a cosmic string. We obtain an instanton describing this process from the $C$ metric, and calculate its probability. This is very low for the strings that have been suggested for galaxy formation.

9 pages, Latex, no figures. Major revision: we have retracted our argument that splitting of topologically stable strings is impossible
