Abstract
We compare the predictions of the collinear parton model and the kT-factorization approach in J/Ψ and D★ meson photoproduction at HERA energies. It is shown that obtained D★ meson spectra over pT and η are very similar in the parton model and kT-factorization approach and they underestimate the experimental data. Opposite, the predictions of the both approaches for pT- and z-spectra in the J/Ψ photoproduction are very different as well as the prediction obtained for the spin parameter α(pT).
