Vector meson production in the Golec-Biernat Wüsthoff model

Abstract We apply the Golec-Biernat Wusthoff model in the calculation of vector meson photo- and electroproduction. Starting from very simple non-relativistic wave functions we show that the model provides a good description of J / Ψ cross sections in wide Q 2 and W ranges. For the light mesons one obtains the approximately correct W -dependence and ratio of longitudinal to transverse cross sections, although in this case the normalization, affected mainly by the wave function employed, is not in good agreement with data.
