Higher twists in the pion structure function

High Energy Physics - Phenomenology 2014-11-17 v1 Nuclear Theory

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.
