The estimation of the number of photon+jet events suitable for determination of gluon distribution inside a proton in a new kinematic region of x, Q^2 variables beyond the one covered by HERA data is also presented.17 pages, 2 figuresHigh Energy Physics - Experimentphoton+jet process application for setting the absolute scale of jet energy and determining the gluon distribution at the LHCtext
