On charmonia and charmed mesons photoproduction at high energy
V. A. Saleev, D. V. Vasin
Abstract
We compare the predictions of the collinear parton model and the kT-factorization approach in JΨand D meson photoproduction at HERA energies. It is shown that obtained in the both approaches D meson spectra over pT and ηas well as JΨmeson pT- and z-spectra are very different. The predictions obtained in the kT-factorization approach are agree with the experimental data well. We also predict the nontrivial pT-dependence of the the spin parameter $α(pT) in the JΨphotoproduction.
