| Jun 21, 2020 at 22:38 | comment | added | 4xion | If your issue is with the terminology, and that 't Hooft anomalies should really be referred to as global anomalies and the chiral anomaly is sort of a mixed anomaly, then I'm sympathetic to that. | |
| Jun 21, 2020 at 22:34 | comment | added | 4xion | I wasn't being so precise above, but (as you probably know) 't Hooft anomalies are an obstruction to promoting a global symmetry to a gauge symmetry. For global anomalies like the chiral anomaly, there is a global current which is not conserved. For a global symmetry with an 't Hooft anomaly, the current is still conserved, the issue arises when we try to gauge the symmetry. | |
