Reheating and Cosmic String Production
arXiv:0707.0908 · doi:10.1016/j.nuclphysb.2008.03.011
Abstract
We compute the string production rate at the end of inflation, using the string spectrum obtained in \lss in a near-de Sitter space. Our result shows that highly excited strings are hardly produced, thus the simple slow-roll inflation alone does not offer a cosmic string production mechanism.
