Abstract We present a Monte Carlo generator for exclusive vector meson production in charged lepton-proton interactions, l + p → l + p + V, based on a QCD leading logarithm model calculation according to which the cross section for this process is proportional to the square of the gluon momentum density in the proton. The generator can be used for both fixed target and collider kinematics. Each event is assigned a weight equal to its cross section, so that the independent variables can be generatedd a... Title of program: DIPSI version 2.4 Catalogue Id: ADEG_v1_0 Nature of problem The reaction e(mu) + p -> e(mu) + p + V, in which an electron or a muon scatters from a proton and a vector meson is produced, can be described as follows. The virtual photon radiated by the lepton fluctuates into a quark-antiquark pair which then interacts with the proton via pomeron exchange. This reaction may allow the investigation of the properties of the pomeron as well as of the hadronic features of the photon. The electron-proton collider HERA at DESY has opened the possibility of studyi ...
