Title: {pi}-{eta} mixing from QCD sum rules

Abstract

The q{sub 2} dependence of the {pi}-{eta} mixing amplitude is examined with the use of QCD sum rules. The linear slope of the mixing function {theta}(q{sup 2}) is found to be much smaller than that for {rho}-{omega} mixing. Thus the mixing amplitude is approximately the same in the space-like region as in the time-like one, and one may neglect the q{sup 2} dependence of the mixing. A comparison between a hadron-meson, an effective chiral model, and the QCD sum rules approaches is made.
