photon+jet process application for setting the absolute scale of jet   energy and determining the gluon distribution at the LHC
  The possibility of jet energy scale setting at the CMS calorimeter by using photon+jet process is studied.   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.
