Abstract

We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed O(1/Q(2) terms in the Wandzura-Wilczek-type approximation, which consists in systematically assuming that (q) over bar gq-terms are much smaller than (q) over barq-correlators. We compute all twist-2 and twist-3 structure functions and the ...
