Cusp Annihilation on Ordinary Cosmic Strings

Abstract

The order of magnitude of energy emission from cusps to light bosons on ordinary cosmic strings is calculated perturbatively. The analysis is applicable to both closed string loops and long cosmic strings. The perturbative result obtained here is much less than what is found by non-perturbative approximations.
