MEASUREMENT OF THE INCLUSIVE ISOLATED PROMPT PHOTON PRODUCTION AT sqrt{s} = 7 TeV WITH THE ATLAS DETECTOR FOR THE 2011 DATASET
Abstract
A measurement of the cross section for the inclusive
production of isolated prompt photons in $pp$ collisions at a
center-of-mass energy $\sqrt{s} = 7\TeV$ is presented. The
measurement covers the pseudorapidity ranges $|\eta^\gamma|<1.37$
and $1.52\leq|\eta^\gamma|<2.37$, in the transverse energy range
$100\leq\ET^{\gamma}<1000 \GeV$. The results are based on an
integrated luminosity of 4.6~\ifb\ collected with the ATLAS detector
at the LHC.
The results are compared with next-to-leading order perturbative QCD
calculations with CT10 and MSTW2008NLO PDFs,
as well as two leading order Monte Carlo PYTHIA and HERWIG.
