The Off Shell -ω Mixing in the QCD Sum Rules
Abstract
The q2 dependence of the -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 m2 > 0 and is negative in the space like region. Implications of this result to the isospin breaking part of the nuclear force are discussed.
