Are tiny gauge couplings out of the Swampland?
Abstract There is significant evidence suggesting that continuous global symmetries are always gauged in quantum gravity. However, very weakly gauged symmetries seem global to an effective field theory expansion in powers of Newton’s constant. We show that, at least for Einsteinian quantum gravity o...
