Abstract

The 1H(e,e'π+)n cross section was measured for arange of four-momentum transfer up to Q2=3.91 GeV2 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 factorization theorem is applicable at rather low values of Q2. The transverse term falls off slower than the naive Q-8 expectation and remains appreciable even at Q2=3.91 GeV2.
