Аннотация:In the framework of semihard QCD approach we consider the processes of inelastic heavy quarkonium photoproduction at HERA with emphasis on the BFKL dynamics of gluon distributions. We investigate the dependences of total cross section of inelastic heavy quarkonium photoproduction and also pt and z spectra from unintegrated gluon distributions. It is shown the total cross section is more sensitive to the Pomeron intercept parameter Delta. We present a comparision of the theoretical results with available H1 and ZEUS experimental data and derive an estimation for the value of Delta.
