Higgs boson production at hadron colliders with kT factorization

The Higgs boson production at high-energy hadron colliders in the framework of the kT-factorization approach is considered. The attention is focused on the dominant gluon-gluon fusion subprocess. The total and differential cross sections of the inclusive Higgs boson production and the dependence of obtained results on different forms of the unintegrated gluon distribution in a proton are calculated. It is demonstrated that leading-order kT factorization gives a possibility to investigate the associated Higgs boson and jets production. In particular, the Higgs-jet and jet-jet azimuthal correlations in the Higgs + one or two jet production processes are calculated
