abstract: 'We test several BFKL-like evolution equations for unintegrated gluon distributions against forward-central dijet production at LHC. Our study is based on fitting the evolution scenarios to the LHC data using the high energy factorization approach. Thus, as a by-product, we obtain a set of LHC-motivated unintegrated gluon distributions ready to use. We utilize this application by calculating azimuthal decorrelations for forward-central dijet production and compare with existing data.'

Introduction
============

A typical procedure in applying QCD to hadronic collisions relies on factorization theorems. They consist in two ingredients: a perturbatively calculable hard part and a nonperturbative piece parametrizing hadrons participating in a collision. The most known and tested is the collinear factorization (see e.g. [@Collins:2011zzd] for a review), which applies for a variety of processes, including jet observables
