  We calculate several differential cross sections for Z0 and high-pT jet
production in the forward rapidity region at the LHC using the hybrid High
Energy Factorization. We test various unintegrated gluon distributions
involving subleading BFKL effects (such as kinematic constraint, running strong
coupling and DGLAP correction) and compare the results with experimental data
obtained by the LHCb experiment. We find that the hard scale dependence of
unintegrated gluon distributions, which effectively resums the Sudakov-type
logarithms on the top of the resummation of the small x logarithms, is
essential to describe the normalized azimuthal decorrelations between the
Z0-boson and the jet.
