Braun, Vladimir M. and Ivanov, Dmitri and Peters, Andreas (2008) Threshold pion electroproduction at large momentum transfers. Physical Review D 77 (3), 034016.
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 are given taking into account P-wave contributions that, as we argue, are model ...
