Gauge Anomaly
... In theoretical physics, a gauge anomaly is an example of an anomaly it is an effect of quantum mechanics—usually a one-loop diagram—that invalidates the gauge symmetry of a quantum field ... of a gauge theory ... Anomalies in gauge symmetries lead to an inconsistency, since a gauge symmetry is required in order to cancel unphysical degrees of freedom with a negative norm (such as a photon polarized ...
