Separation of quark and gluon jets in the direct photon production processes at the LHC using the neural network approach
D. V. Bandourin, N. B. Skachkov
A neural network technique is used to discriminate between quark and gluon jets produced in the qg->q+photon and q q->g+photon processes at the LHC. Considering the network as a tr…
On the possibility of discrimination between mesons and a photon based on the calorimeter information in the CMS detector
D. V. Bandourin, V. F. Konoplyanikov, N. B. Skachkov
The possibility of separating the and meson background from the signal photons produced directly in collisions is analyzed. The rejection factors for two p…

D. V. Bandourin, V. F. Konoplianikov, N. B. Skachkov
In this paper the study of "photon+Jet" events is continued, aimed at jet energy scale setting and hadron calorimeter calibration at LHC energies. The event number distribution ove…
Jet energy scale setting with "photon+Jet" events at LHC energies. Generalities, selection rules
D. V. Bandourin, V. F. Konoplianikov, N. B. Skachkov
"photon+Jet" events, based on the q~q-> g+photon and qg-> q+photon subprocesses, are proposed for jet energy scale setting and hadron calorimeter calibration at LHC energies. Gener…
Jet energy scale setting with "photon+Jet" events at LHC energies. Minijets and cluster suppression and photon Pt - jet Pt disbalance
D. V. Bandourin, V. F. Konoplianikov, N. B. Skachkov

Jet energy scale setting with "Gamma+Jet" events at LHC energies. Detailed study of the background suppression
D. V. Bandourin, V. F. Konoplyanikov, N. B. Skachkov
The possibilities of the background events suppression, based on the QCD subprocesses of qg-, gg-, qq- scattering with big cross sections, to the signal \gpj events are studied. Ba…
