Query: CP-violating CFT and trace anomaly   It is logically possible that the trace anomaly in four dimension includes
the Hirzebruch-Pontryagin density in CP violating theories. Although the term
vanishes at free conformal fixed points, we realize such a possibility in the
holographic renormalization group and show that it is indeed possible. The
Hirzebruch-Pontryagin term in the trace anomaly may serve as a barometer to
understand how much CP is violated in conformal field theories.
