Radiation of Goldstone bosons from cosmic strings

Alexander Vilenkin, Tanmay Vachaspati

Open publisher page 174 citations

Abstract

It is shown that the interaction of global strings with Goldstone bosons can be described by a model of strings coupled to an antisymmetric tensor field with a particular choice of the coupling constant. This formalism is applied to calculate the rate of Goldstone-boson radiation from a class of closed-loop trajectories. The lifetime of a typical loop is found to be very short, about twenty oscillation periods, in agreement with an earlier estimate by Davis.
