Title: Off-shell [rho]-[omega] mixing in QCD sum rules

Abstract

The [ital q][sup 2] dependence of the [rho]-[omega] mixing amplitude is analyzed with the use of QCD sum rules and dispersion relations. Going off shell the mixing decreases, changes sign at [ital q][sup 2][congruent]0.4[ital m][sub [rho]][sup 2][gt]0, and is negative in the spacelike region. Implications of this result for the isospin breaking part of the nuclear force are discussed.
