Pionic measures of parity and [formula presented] violation in high energy nuclear collisions

The collisions of large nuclei at high energies could produce metastable vacua which are odd under parity P, charge conjugation C, and/or (Formula presented) Using only the three-momenta of charged pions (or kaons), we show how to construct global observables which are odd under P C, and (Formula presented) and which can be measured on an event by event basis. Model dependent estimates of the P-odd observables are on the order of (Formula presented)
