Abstract: (arXiv)

We consider the central exclusive production of

q\bar{q}

pairs and Higgs boson at proton-proton collisions at LHC. The amplitude for the process is derived within the

k_{\perp}

-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_{\perp}

distributions, invariant

q\bar{q}

mass distributions, angular azimuthal correlations between outgoing protons and jets are presented. Irreducible

b{\bar b}

background to the central exclusive Higgs boson production is analyzed in detail, in particular how to impose cut to maximize signal-to-background ratio.
