| Özet |
| A measurement of the cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of TeV is presented. The measurement covers the pseudorapidity ranges| η γ|< 1. 37 and 1. 56≤| η γ|< 2. 37 in the transverse energy range 25< E γ T< 1500 GeV. The results are based on an integrated luminosity of 20.2 fb− 1, recorded by the ATLAS detector at the LHC. Photon candidates are identified by combining information from the calorimeters and the inner tracker. The background is subtracted using a data-driven technique, based on the observed calorimeter shower-shape variables and the deposition of hadronic energy in a narrow cone around the photon candidate. The measured cross sections are compared with leading-order and next-to-leading order perturbative QCD calculations and are found to be in a good agreement over ten orders of magnitude. |
