DIPSI - A MONTE-CARLO GENERATOR FOR ELASTIC VECTOR-MESON PRODUCTION IN CHARGED LEPTON-PROTON SCATTERING

We present a Monte Carlo generator for exclusive vector meson producti on in charged lepton-proton interactions, l + p --> l + p + V, based o n a QCD leading logarithm model calculation according to which the cro ss section for this process is proportional to the square of the gluon momentum density in the proton. The generator can be used for both fi xed target and collider kinematics. Each event is assigned a weight eq ual to its cross section, so that the independent variables can be gen erated according to convenient distributions, not necessarily identica l to the physics ones.
