Charm-Anticharm Kinematical Correlations in Photon-Proton Scattering
Abstract
c- c correlations are calculated in the kt-factorization approach. Different unintegrated gluon distributions (uGDF) from the literature are used. The results are compared with recent results of the FOCUS collaboration. The recently developed CCFM uGDF gives a good description of the data. Predictions for the HERA energies are presented.
