Pseudoscalar mesons and instantons
Description
We discuss the QCD sum rules for the correlation of pseudoscalar currents with quantum numbers of π, K, eta, eta' mesons. In the framework of the instanton model of the QCD vacuum suggested earlier by the author, we calculate SU(3) breaking effects such as K, eta masses and etaeta' mixing, as well as the U(1) breaking effect, the eta' mass. We conclude that all these phenomena are very well reproduced by this model. (orig.)
