description: The results of Monte Carlo calculation of cross section ratios of hadron dijet production, as functions of rapidity separation between jets in the dijet, in proton-proton collisions at center of mass energy 2.76, 8, 13, 14, 27 and 100 TeV, which are available at the Large Hadron Collider (LHC) and future proton-proton colliders. The Monte Carlo simulation is performed with packages based on evolution equations of DokshitzerâGribovâLipatovâ AltarelliâParisi such as PYTHIA8 and HERWIG++, as well as with package HEJ+ARIADNE which is based on evolution equations of BalitskyâFadinâKuraevâLipatov (BFKL). The results allow to draw conclusion about sensibility of the studied set of physical observables to BFKL evolution and possibility of its observation at the LHC and future proton-proton colliders. The methods of unfolding are discussed in application to measurement of ratios of dijet production cross sections in proton-proton collisions at center of mass energy 2.76 TeV at the CMS (Compact Muon Solenoid) detector at the LHC. The bin-by-bin, matrix inversion, TUnfold, SVD unfolding and DâAgositni unfolding are considered. The optimal scheme of correction for detector effects is built.
