摘 要：

In this talk I will be discussing the stability of loops of superconducting cosmic string, known as vortons, to non-axially symmetric perturbations. By calculating a few integrated quantities of straight string solutions we can accurately predict the stability properties of vortons, if they are large enough that the effects of curvature can be neglected. Using this analysis, we have predicted the existence of stable vortons and performed supporting 3D simulations by perturbing our constructed solutions.
