Abstract
A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy s=7TeV is presented. The results are based on an integrated luminosity of 4.6fb-1 collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity ���� and transverse energy ET�� in the kinematic range 100���ET��<1000GeV and in the regions |����|<1.37 and 1.52���|����|<2.37. The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading-order perturbative QCD calculations. Next-to-leading-order perturbative QCD calculations agree well with the measured cross sections as a function of ET�� and ����. �� 2014 CERN, for the ATLAS Collaboration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
