Electroproduction of Hadrons from Deuterium

Abstract

The inclusive electroproduction of hadrons is measured from hydrogen and deuterium targets. The exchanged virtual photons are in the kinematic range $-0.25>q^2>-3.00\mathrm{}$ ${\mathrm{GeV}}^2$, $12<s<\mathrm{}30\mathrm{}$ ${\mathrm{GeV}}^2$. Hadrons which travel in the direction of the virtual photon in the virtual-photon-nucleon c.m. system are detected. A striking difference from photoproduction is observed in the excess of positive relative to negative hadrons from both proton and neutron targets.
