Phys. Rev. Lett. 84, 4288–4291 (2000)Radiation from Cosmic String Standing WavesReceived 18 October 1999; published in the issue dated 8 May 2000 We have simulated large-amplitude standing waves on an Abelian-Higgs cosmic string in classical lattice field theory. The radiation rate falls exponentially with wavelength, as one would expect from the field profile around a gauge string. Our results agree with those of Moore and Shellard, but not with those of Vincent, Antunes, and Hindmarsh. The radiation rate falls too rapidly to sustain a scaling solution via direct radiation of particles from string length. There is thus reason to doubt claims of strong constraints on cosmic string theories from cosmic ray observations. © 2000 The American Physical Society URL:
