Jet energy scale setting with "photon+Jet" events at LHC energies. Minijets and cluster suppression and photon Pt - jet Pt disbalance

In this paper the study of "photon+Jet" events is continued and the event number determination useful for jet energy scale setting with the possible CMS detector hadron calorimeter calibration at LHC is fulfiled. The sources of photon Pt and jet Pt disbalance are exposed. It is shown that the cluster Pt limitation, which is found in an event outside of the jet, can be a good criterion for this disbalance decreasing.
