Inverse pion electroproduction at high energies- a source of information on the hadron form factors

Processes γN→π±N, eN→eπ±N, πN→e+e-N, π-p→ρ0n are considered in the framework of the unified dispersive model at high energies and small momentum transfer. A conclusion is drawn on the reduction of the rescattering effects with increasing time-like values of virtual photon mass. Thus simple electric Born model for the description of the process of inverse electroproduction (and π-p→ρ0n) in indicated kinematic region is grounded and conclusion on the possibility of receiving reliable information on hadron structure from the experimental data on this process is drawn. 27 refs.; 1 fig
