Abstract

We consider the central exclusive production of qq¯ pairs and Higgs boson in proton-proton collisions at LHC. The amplitude for the process is derived within the k⊥-factorization approach and considered in different kinematical asymptotics, in particular, in the important high quark transverse momenta and massless quark limits. Quark helicity and spin-projection amplitudes in two different frames are shown in extenso. Rapidity distributions, quark jet p⊥ distributions, invariant qq¯ mass distributions, angular azimuthal correlations between outgoing protons and jets are presented. Irreducible bb¯ background to the central exclusive Higgs boson production is analyzed in detail, in particular, how to impose cuts to maximize signal-to-background ratio.
