Preserved Fulltext
We consider pion electroproduction on a proton target close to threshold for Q 2 in the region 1 10 GeV 2 . The momentum transfer dependence of the S-wave multipoles at threshold, E 0· and L 0· , is calculated using light-cone sum rules. Predictions for the expected cross sections in the near-threshold region are presented based on a simple model taking into account S-and P-waves.
