Abstract
Deeply virtual electroproduction of pions in an exclusive reaction p(e,e{sup '}{pi}{sup +})n is studied using a two-component model that includes soft hadronic and hard partonic reaction mechanisms. The results are compared with the experimental data measured at HERMES in the deep inelastic region for values of Q{sup 2}>1 GeV{sup 2} and W{sup 2}>10 GeV{sup 2}. At forward angles the {pi}{sup +} cross section is longitudinal and is dominated by exchange of Regge poles, with {pi} being the dominant trajectory. The off-forward region with -t>1 GeV{sup 2} is transverse and shows the dominance of partonic subprocesses. An implication of the present results for the future JLab facilities is briefly discussed.
