"photon+Jet" events rate estimation for gluon distribution determination   at LHC
  It is shown that "photon+Jet" events, being collected at LHC, would provide us with the data sufficient for an extraction of gluon distribution function in a proton using valence and s quark distributions measured in the same experiment with another physical proces A new region of 10^{-4}< x < 10^{-1} with 1.6x10^3< Q^2<10^5 ~(GeV/c)^2 can be covered. The rates of g c-> photon +Jet events are also given.
