Abstract

We consider the central exclusive production of qq̄ 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 qq̄ mass distributions, angular azimuthal correlations between outgoing protons and jets are presented. Irreducible bb̄ background to the central exclusive Higgs boson production is... (More)

Irreducible bb̄ background to the central exclusive Higgs boson production is analyzed in detail, in particular, how to impose cuts to maximize signal-to-background ratio. © 2011 American Physical Society.
