# Irreducible cosmic production of relic vortons

@article{Auclair2020IrreducibleCP, title={Irreducible cosmic production of relic vortons}, author={Pierre Auclair and Patrick Peter and Christophe Ringeval and Dani{\`e}le Steer}, journal={Journal of Cosmology and Astroparticle Physics}, year={2020}, volume={2021} }

The existence of a scaling network of current-carrying cosmic strings in our Universe is expected to continuously create loops endowed with a conserved current during the cosmological expansion. These loops radiate gravitational waves and may stabilise into centrifugally supported configurations. We show that this process generates an irreducible population of vortons which has not been considered so far. In particular, we expect vortons to be massively present today even if no loops are…

Cosmic strings formed during inflation are expected to be either diluted over super-Hubble distances, i.e., invisible today, or to have crossed our past light cone very recently. We discuss the…

The first ever evidence of stable vortons is given and impacts several branches of physics where they could potentially exist and range from cosmology, since vorton could perhaps contribute to dark matter, to QCD and condensed matter physics.
