The J/Ψ electro- and photoproduction at high energies and the gluon distribution of the proton
Description
This presents the calculations of the J/Ψ photo- and electroproduction cross sections on protons made in two different QCD models for different gluon distribution functions of the proton. It is shown that these gluon distributions lead to different J/Ψ production cross sections at HERA energies. 31 refs.; 10 figs
