Zooming in on Strings and Vortons


Virtual workshop at CERN

Cosmic strings represent an intriguing class of topological defects that form in many scenarios of new physics in the early Universe. Recently, the possibility of cosmic strings supporting a nonvanishing current at their core has attracted some attention in the literature. In particular, it has been pointed out that current-carrying cosmic strings can evolve into an ensemble of effectively stable remnants called vortons. The purpose of this two-hour impromptu workshop is to review the dynamics of current-carrying cosmic strings, vortons, and their implications for other aspects of physics beyond the standard model such as dark matter and axion physics.


Each talk will consist of a 15' presentation and 15' for discussion. All presentations will be recorded and uploaded to The discussion sessions will not be recorded.

We strongly encourage everyone interested in this meeting to register so that we can gauge the expected size of the audience.
