AbstractAbstract
[en] The q2 dependence of the ρ - ω mixing amplitude is analyzed with the use of the QCD sum rules and the dispersion relation. Going off shell the mixing decreases, changes sign at q2 ≅ 0.4 mp2 > 0 and is negative in the space like region. Implications of this result to the isospin breaking part of the nuclear force are discussed. (author)
