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.
