Mueller-Navelet small-cone jets at LHC in next-to-leading BFKL

We consider within QCD collinear factorization the process p+p→jet+jet+X, where two forward high-pT jets are produced with a large separation in rapidity Δy (Mueller-Navelet jets). In this case the (calculable) hard part of the reaction receives large higher-order corrections ∼αsn(Δy)n, which can be accounted for in the BFKL approach with next-to-leading logarithmic accuracy, including contributions ∼αsn(Δy)n−1. We calculate several observables related with this process, using the next-to-leading order jet vertices, recently calculated in the approximation of small aperture of the jet cone in the pseudorapidity-azimuthal angle plane.
