Pomeron intercept from BFKL gluon dynamics in deep inelastic charm production at HERA

Abstract

In the framework of semihard (k${}_T$ factorization) QCD approach, we consider the differential cross sections of $D^{\ast \pm }$ meson production at HERA. The consideration is based on BFKL and CCFM gluon distributions. We find that in the case of BFKL LO gluon distribution the theoretical results are sensitive to the Pomeron intercept parameter $\Delta$. We present a comparison of the theoretical results with available ZEUS experimental data.
