Abstract In SU(N ) gauge theory, it is argued recently that there exists a “mixed anomaly” between the CP symmetry and the 1-form ℤ N $$ {\mathbb{Z}}_N $$ symmetry at θ = π, and the anomaly matching requires CP to be spontaneously broken at θ = π if the system is in the confining phase. In this pape...
