Title: Vector meson production in the Golec-Biernat Wusthoff model
Author: Caldwell, AC
Soares, MS
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/psi 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.
