Estimates of higher-dimensional vacuum condensates from the instanton vacuum
arXiv:hep-ph/9710534 · doi:10.1103/PhysRevD.57.4471
Abstract
We calculate the values of non-factorizable dimension-7 vacuum condensates in the instanton vacuum. We comment on a method, recently proposed by Oganesian, to estimate the dimension-7 condensates by factorization of dimension-10 condensates in various inequivalent ways. The instanton estimates could be used to analyze the stability of QCD sum rules with increasing dimensions.
