| Jul 26, 2018 at 14:41 | comment | added | knzhou | @apt45 I'm not asking "can a non-gauged symmetry be anomalous", rather I am asking "can a global symmetry be anomalous in a theory with no gauge fields at all". | |
| Jul 26, 2018 at 14:40 | comment | added | apt45 | Just a comment which may help. Consider the anomalous chiral symmetry in QCD (the anomaly which would lead you to introducing che axion). The chiral rotation is absolutely global but the measure of the path integral is not invariant. The anomaly is proproprional to the SU(3) gauge filed strengths, or to $G\tilde{G}$. There is no gauge field associated to the chiral symmetry. | |
