We consider a 4d non-linear sigma model on the coset (SU(N)L × SU(N)R × SU(2))/(SU(N)L+R × U(1)) ∼= SU(N) × S
2, that features a topological Wess–Zumino–Witten (WZW) term whose curvature is n/24π2 Tr(g−1dg )3 ∧ VolS2 where g is the SU(N)
pion field... Read More about WZW terms without anomalies: Generalised symmetries in chiral Lagrangians.

We present a new non-perturbative ’t Hooft anomaly afflicting a quantum field theory with symmetry group G = U(1) × ℤ2 in four dimensions. We use the Adams spectral sequence to compute that the bordism group (BG), which classifies anomalies that rema...
