Averaged methods for vortex-string evolution

C. J. A. P. Martins, E. P. S. Shellard

Abstract
We discuss friction-dominated vortex-string evolution using an analytic model recently developed by the authors. By treating the average string velocity, as well as the characteristic lengthscale, as dynamical variables, we can provide a quantitative picture of the complete evolution of a vortex-string network. Previously known scaling laws are confirmed, and quantitative predictions regarding loop production and evolution are made.
