Description
Superconducting cosmic strings are intriguing relics of high-energy physics beyond the Standard Model, with the potential to leave observable imprints in the form of gravitational waves. In this talk, I will present recent progress on the stochastic gravitational wave background generated by chiral superconducting cosmic string networks. For the first time, we incorporate the effects of vector radiation emitted by these strings, which influence loop evolution and, consequently, alter the resulting observational predictions.
Our results show that strong coupling between the string current and the vector field can lead to a significant suppression of the gravitational wave signal. However, in the regime of intermediate coupling, the signal remains detectable—offering a potential observational distinction between standard and superconducting cosmic strings.
