We consider the central exclusive production of q (q) over bar pairs and Higgs boson in proton-proton collisions at LHC. The amplitude for the process is derived within the k(perpendicular to)-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(perpendicular to) distributions, invariant q (q) over bar mass distributions, angular azimuthal correlations between outgoing protons and jets are presented. Irreducible b (b) over bar background to the central exclusive Higgs boson production is analyzed in detail, in particular, how to impose cuts to maximize signal-to-background ratio.
