Higher twists in the pion structure function

arXiv:hep-ph/0303140 · doi:10.1103/PhysRevD.67.077502

Abstract

We calculate the QCD moments of the pion structure function using Drell-Yan data on the quark distributions in the pion and a phenomenological model for the resonance region. The extracted higher twist corrections are found to be larger than those for the nucleon, contributing around 50% of the lowest moment at Q^2=1 GeV^2.
