CERN-LHC. Measurement of the inclusive isolated prompt photon cross section in pp collisions at 8 TeV with the ATLAS detector.
The prompt photon fiducial region is defined as:
- ET(Photon) range: 25 < ET(Photon) < 1500 GeV
- |EtaPhoton|: 0-0.6, 0.6-1.37, 1.56-1.81, 1.81-2.37
- Photon Isolation in DeltaR-Cone of 0.4: ETIso < 4.8 GeV + 4.2x10^{-3} ET(Photon). At particle level it is the sum of transverse energy from all particles, except for muons, neutrinos and the photon itself. At parton level it is the sum of energy from all coloured partons.
