Abstract

A nonperturbative calculation of elastic electroproduction of the J/ψ meson is presented and compared to the experimental data. Our model describes well the observed dependences of the cross sections on the photon virtuality Q2 and on the energy, and the measured ratio R=σL/σT of longitudinal to transverse cross sections.
