Abstract:
The exclusive electroproduction of pi(+) mesons was studied with the HERMES spectrometer at the DESY laboratory by scattering 27.6 GeV positron and electron beams off an internal hydrogen gas target. The virtual-photon cross sections were measured as a function of the Mandelstarn variable t and the squared four momentum -Q(2) of the exchanged virtual photon. A model calculation based on Generalized Parton Distributions is in fair agreement with the data at low values of It I if power corrections are included. A model calculation based on the Regge formalism gives a good description of the magnitude and the t and Q(2) dependences of the cross section. (c) 2007 Elsevier B.V. All rights reserved.
