Dijets with large rapidity separation at CMS

A search for asymptotic BFKL effects at CMS in dijet events with large rapidity separation between jets in proton-proton collisions at 7 TeV is presented. CMS data on cross-section ratios and azimuthal decorrelations for dijets with large rapidity separation between jets are compared with predictions by various Monte Carlo event generators based on DGLAP and BFKL evolutions. None of the DGLAP-based generators can describe all measured observables by CMS at 7 TeV. NLO BFKL predictions are consistent with CMS data on dijet azimuthal decorrelations at 7 TeV. More data at higher LHC energies are needed to reveal possible effects.
