Web1 Answer. Sorted by: 15. There is no chiral anomaly / gauge anomaly if the spacetime dimension 2 ℓ + 1 is odd, partly because S O ( 2 ℓ + 1) has real or pseudo-real representations, but no complex representations. There may instead be parity anomalies in odd spacetime dimensions. In fact, there is a dimensional ladder of related anomalies.
