Contribution of Quark-Mass-Dependent Operators to Higher Twist Effects in DIS

Abstract

We look at the contribution of Quark-Mass-dependent twist-4 operators to the second moments of spin averaged structure functions and the Bjorken sum rule. Its contribution is non-negligible in the former case due to large Wilson coefficients. We also discuss the values of the twist- 4 spin-2 nucleon matrix element within present experimental constraints.
