Gluon Distributions

We discuss and compare different approaches to include gluon transverse momenta for heavy quark-antiquark pair and meson production. The results are illustrated with the help of different unintegrated gluon distributions (UGDF) from the literature. We compare results obtained with on-shell and off-shell matrix elements and kinematics. The results are compared with recent experimental results of the CDF collaboration.

Gluon Distributions

We review and discuss the use of TMD, or "unintegrated", gluon distributions in the domain of small-x physics. The definitions employed, and the hazards of the naive applications of the TMD factorization and the associated gluon distributions are discussed.

Theoretical Results

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 the total cross-section of inelastic J/Ψ photoproduction and also pT and z spectra on different forms of the unintegrated gluon distribution. It is shown that the total cross-section is most sensitive to the Pomeron intercept parameter Δ. We compare the theoretical results with the available H1 and ZEUS experimental data.
