Small-x dynamics in forward–central dijet correlations at the LHC
We provide a description, within the High Energy Factorization formalism, of central–forward dijet correlation data measured by the CMS experiment and the predictions for nuclear modification ratio RpA in p + Pb collisions.

| Summary: | We provide a description, within the High Energy Factorization formalism, of central–forward dijet correlation data measured by the CMS experiment and the predictions for nuclear modification ratio RpA in p + Pb collisions. In our study, we use the unintegrated gluon density derived from the BFKL and BK equations supplemented with subleading corrections and a hard scale dependence. The latter is introduced at the final step of the calculation by re-weighting the Monte Carlo generated events using suitable Sudakov form factors, without changing the total cross section. We achieve a good description of data in the whole region of the azimuthal angle. |
