Abstract
Processes of heavy quark photoproduction at HERA energies are considered using the semihard (kT factorization) QCD approach with emphasis of the BFKL dynamics of gluon distributions. We investigate the dependences of the total cross section of heavy quark photoproduction and also pT, and rapidity distributions on different forms of the unintegrated gluon distribution. We present a comparision of the theoretical results with available H1 and ZEUS experimental data for charm and beauty photoproductions.
