The consequences of application of new set of criteria, proposed in our previous works, for the improvement of a jet energy calibration accuracy with the process p~p->photon+jet+X at Tevatron and for a reduction of background events contribution are studied. The efficiencies of the used selection criteria are estimated. The distributions of these events over photon Pt and jet pseudorapidity are presented. The features of photon+jet events in the central calorimeter region of the D0 detector (|eta|<0.7) are investigated. It is also shown that the samples of photon+jet events, selected with the cuts used for the jet energy calibration, may have the statistics sufficient for determining the gluon distribution function of a proton in the region of 2*10^{-3}< x < 1.0 and the values of Q^2 by one order higher than that reached in the experiments at HERA. Monte Carlo events produced by the PYTHIA 5.7 generator are used for this aim.

A possibility of jet energy scale setting by help of ``p p -> Z0+jet+X process at LHC is studied. The effect of new set of cuts, proposed in our previous works, on the improvement of the Pt balance between Z0 boson and jet is demonstrated. The distri
The number of photon+jet and Z+jet events suitable for a determination of gluon distribution function in a proton at Tevatron Run II and during the low luminosity runs at future LHC experiments are estimated for various intervals of x and Q^2. These
It is shown that the samples of Z0+jet events, collected at the LHC with the integrated luminosity L_{int}=20 fb^{-1}, may have enough statistics for determining the gluon distribution inside a proton in the region of 2*10^{-4} < x < 1.0 at Q^2 value
The DZERO detector is used to study proton-antiproton collisions at the 1800 GeV and 630 GeV center-of-mass energies available at the Fermilab Tevatron. To measure jets, the detector uses a sampling calorimeter composed of uranium and liquid argon as
