Vacuum expectations of the high dimensional operator and their contribution in Bjorken and Ellis-Jaffe sum rules

Abstract

The method of estimation of the unknown high-dimensional vacuum averages is offered. This method is based on the idea of self-consistence of the factorization hypothesis. So it appears possible to evaluate all vacuum averages of dimension 7 and also get some estimations for vacuum averages of dimension 10. Obtained results are used to calculate high dimensional operator contribution to Bjorken and Ellis-Jaffe sum rules.
