Abstract

The electroproduction of charged ρ mesons on a nucleon under conditions of quasielastic kinematics (Q 2 = 2−3 (GeV/c)2, W = 2 GeV) is considered. Dominant diagrams are taken into account. It is shown that the transverse cross section for ρ-meson knockout, in just the same was as the respective longitudinal cross section, is dominated by the t-pole diagram involving a virtual ρ meson. This means that the leading contribution to the process comes from direct ρ-meson knockout.
