Abstract (data abstract)
CERN-LHC. The production cross section of inclusive isolated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at a centre-of-momentum energy of $\sqrt{s}=7~\mathrm{TeV}$. The measurement is performed with the electromagnetic calorimeter EMCal and the central tracking detectors covering a range of $|\eta| < 0.27$ in pseudorapidity and a transverse momentum range of $10<p_\mathrm{T}^{\gamma}<60$~GeV/$c$. The result extends the coverage of previously published results of the ATLAS and CMS experiments at the same collision energy to smaller $p_\mathrm{T}^{\gamma}$. The measurement is compared to next-to-leading order perturbative QCD calculations and to the results from the ATLAS and CMS experiments. All measurements and theory predictions are in agreement with each other

Version 2 modifications: 3 complementary tables added to ease the reproduction of the paper figures: the theoretical prediction shown in Fig. 8 and used in Fig. 9, the correction factor used to account for the underlying event of the collision in the theory points, and the xT distribution of Fig. 10.
