Abstract
We demonstrate that the non-trivial CP-violating structure of QCD vacu um can lead to an observable effect in e(+) e(-) --> <q(q)over bar> -- > 2-jet annihilation. We find that the sign of the jet handedness corr elation can be opposite to that predicted by factorization of <q(q)ove r bar> fragmentation and CP-conjugation of the two jets. A simple mode l estimation of the handedness correlation magnitude is given.
