Forward dijets and search for new physics at the LHC

Forward dijets and possible signals of hypothetical extra-dimension graviton at the LHC are discussed. Studies for large mass dijet production at s=7 and 14 TeV in forward rapidity region are presented with a model of extra-dimension graviton t-channel exchange in trans-Planckian scattering regime. The model is implemented into Monte Carlo event generator. QCD background for dijets with large effective masses was studied with different Monte Carlo event generators, including BFKL-motivated generators.
