Abstract

We consider the cross section of the deep inelastic pion electroproduction on a proton target at threshold for Q2 in the region 5–10  GeV2. The corresponding amplitudes are described in terms of two form factors which we calculate using light-cone sum rules to leading order in QCD and including higher twist corrections. Our results suggest a considerable change from a small Q2 region that can be ...
