Title Cosmic strings from pure Yang-Mills theory
Abstract I review some properties of pure Yang-Mills theories and explain why color flux tubes can be cosmic strings. Their stability is explained by 1-form center symmetries.Their production in the thermal phase transition is explained by the qualitative picture coming from the electric-magnetic duality. Some of their further properties such as intercommutation probability in the large N limit can be understood by the theory of large N counting and holographic duality. Pure Yang-Mills theories are the simplest and natural models for cosmic strings, and may be observed by future gravitational wave experiments.
