Scaling study of the pion electroproduction cross sections
Scaling study of the pion electroproduction cross sections
The 1H(e,e′π+)n cross section was measured for arange of four-momentum transfer up to Q2=3.91GeV2 at values of the invariant mass W above the resonance region. The Q2 dependence of the longitudinal component was found to be consistent with the Q2-scaling prediction for hard exclusive processes. This suggests that the QCD …
