Measurement of the inclusive isolated prompt photon cross section in pp collisions at √s=8TeV with the ATLAS detector
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 √s=8 TeV is presented. The measurement covers the pseudorapidity ranges |η<sup>γ</sup> | < 1.37 and 1.56 ≤ |η<sup>γ</sup> |...
