What is Exclusive pi^+ production at HERMES about?

Hard exclusive production in deep inelastic lepton scattering provides access to the unknown Generalized Parton Distributions (GPDs) of the nucleon. At HERMES, different observables for hard exclusive pi^+ production have been measured with a 27.6 GeV positron beam on an internal hydrogen gas target. First preliminary results for the unpolarized ep->enpi^+ total cross section for 1.5<Q^2<10.5 GeV^2 and for 0.02<x<0.8 are presented and compared to GPD calculations. The final result for the single-spin asymmetry using a longitudinal polarized target is also reported.
