Vafa-Witten theorem

Vafa-Witten theorem

In theoretical physics, the Vafa-Witten theorem, named after Cumrun Vafa and Edward Witten, is a theorem that shows that vector-like (i.e. those which transform as expected under reflections) global symmetries such as isospin and baryon number cannot be spontanteously broken as long as the theta angle is zero.
