Charm production in the semi-hard approach of QCD and the unintegrated gluon distribution
S. P. Baranov, H. Jung, N. P. Zotov
Abstract
In the framework of semi-hard QCD approach, we present a consistent analysis of D* meson production at HERA energies. The consideration is based on universal unintegrated gluon densities, which have BFKL behavior in the small x region. Predictions of the CCFM evolution equation for D* production are obtained and show a good description of D* data at HERA.
