Overview
We revisit various topological issues concerning 4d Wess-Zumino-Witten terms for SU and SO QCD, from the modern bordism point of view. We explain why the definition of the 4d WZW terms requires the spin structure, and also discuss how the mixed anomaly involving the 1-form symmetry of SO QCD is reproduced in the low-energy sigma model.
