| contents | We study the effects of matching of the high-energy resummation based on the BFKL equation with initial state radiation effects, taken into account within the framework of high-energy factorization, in the production of Mueller-Navelet dijets at hadron colliders. We use the RG-invariant solution of the NLO BFKL equation built out of eigenfunctions perturbatively constructed up to NLO to avoid the need for special renormalization scale setting. We demonstrate that various data sets from the FNAL Tevatron and CERN LHC can be described in this way and both the initial state radiation effects of the high-energy factorization and the NLL BFKL resummation are crucial for the uniform description of the data across all values of the rapidity difference between the jets. The behaviour of angular distributions and ratios of angular coefficients with increasing rapidity separation between the jets provides clear evidence for the NLL BFKL dynamics at the Tevatron and LHC. |
