Could Electromagnetic Corrections Solve The Vorton Excess Problem ?
arXiv:hep-ph/9705204 · doi:10.1103/PhysRevD.57.2580
Abstract
The modifications of circular cosmic string loop dynamics due to the electromagnetic self-interaction are calculated and shown to reduce the available phase space for reaching classical vorton states, thereby decreasing their remnant abundance. Use is made of the duality between master-function and Lagrangian formalisms on an explicit model.
