Operator product expansion coefficient functions in terms of composite operators only. Nonsinglet case

Abstract

A new method for calculating the coefficient functions of the operator product expansion is proposed which does not depend explicitly on elementary fields. Coefficient functions are defined entirely in terms of composite operators. The method is illustrated in the case of QCD nonsinglet operators.

Derivation of the main formula is improved. References are added. To appear in Physical Review D
