Description

I shall discuss phenomenological consequences of merging the proper QCD Sudakov
resummation with small-$x$ effects, which allows us to compute gluon
distributions that depend on longitudinal momentum, transverse momentum and the
hard scale of the process. The small-$x$ resummation is included by means of the
BK equation supplemented with a kinematic constraint and subleading corrections.
The new gluon densities are then used to calculate predictions for
central-forward dijet production at LHC energies within the framework of high
energy factorization. The results are tested against CMS data and compared with
earlier predictions where Sudakov effects came from naive modeling.
