According to ref.1, the Chern-Simons theory SU(N)kSU(N)k has a ZNZN one-form symmetry with anomaly
η=exp[−2πikN](4.12)(4.12)η=exp[−2πikN]
which, apparently, can be computed by from the known value of the conformal dimension of the ZNZN-generator, to wit,
Δ=(N−1)k2N
I hope you like it if yes then make me as brainlist plz plz plz plz
