We consider pion electroproduction close to threshold for Q2 in the region 1–10 GeV2 on a nucleon target. The momentum transfer dependence of the S-wave multipoles at threshold, E0+ and L0+, is calculated in the chiral limit using light-cone sum rules. Predictions for the cross sections in the threshold region, both for π0p and π+n channels, are given that include P-wave contributions that, as we ...
