Irreducible cosmic production of relic vortons
Early October, we released on arxiv a paper together with P. Peter, C. Ringeval and D. Steer in which we calculate the production of vortons in the early Universe.
If you are unfamiliar with the subject, I have been invited to present the paper at the mini-workshop "Zooming in on Strings and Vortons" that was held virtually at CERN on the 22nd of October 2020. The presentation has been recorded and is now on Youtube for you to see. You may also find the slides I used for this presentation here.
