Abstract

We demonstrate that the non-trivial CP-violating structure of QCD vacuum can lead to an observable effect in e+e-→ q q→ 2-jet annihilation. We find that the sign of the jet handedness correlation can be opposite to that predicted by factorization of q~ q fragmentation and CP-conjugation of the two jets. A simple model estimation of the handedness correlation magnitude is given.
