  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 values in the interval of 0.9*10^3 < Q^2 < 4*10^4 ~(GeV/c)^2. A
possibility of the background events suppression by use of the Z^0+jet events
selection criteria is also demonstrated.
