Deep Inelastic Electroproduction — The Photon Fragmentation Region
Abstract
Data are presented on the electroproduction of hadrons. The virtual photons are in the kinematic range -.25 > q2 >-3.00 (GeV/c)2, 6 < W2 < 30 GeV2. Hadrons produced with large laboratory momentum in the direction of the virtual photons are observed. The fraction of elastic ρo mesons with longitudinal polarization is too large to support a vector dominance model for deep inelastic electron scattering. An excess of positive relative to negative hadrons is observed both with proton and with neutron targets. Other electroproduction experiments are reviewed. Finally, it is noted that as scaling turns on between q2 = 0 and q2 =-1 GeV2 the electroproduced hadrons assume a less diffractive character consistent with the quark parton model.
