The Wess-Zumino consistency condition allows more exotic forms of anomalies than those we usually encounter. For example, in two-dimensional conformal field theories in the curved background with spacetime-dependent coupling constant, acurrent could possess anomalous divergence of the form DμJμ=c˜R+χij∂μλi∂μλj+χ˜ijεμν∂μλi∂νλj+⋯. Another example is theodd Pontryagin density in four-dimensional Weyl anomaly. We could, however, argue that they are impossible in conformal field theories because they cannot correspond to any (unregularized) conformally invariant correlation functions. We find that this no-go argument may be a red herring. We show that some of these “impossible anomalies” avoid the no-go argument because they are not primary operators, and the others circumvent it because they are realized as semilocal terms as is the case with the conformally invariant Green-Schwartz mechanism and in the higher dimensional analogue of Liouville or linear dilaton theory.
