Measurement of the Production Cross Section of Pairs of Isolated Photons in pp Collisions at $\surd s$ = 7 TeV

The integrated and differential cross sections of the production of pairs of isolated photons have been measured in proton-proton collisions at a center-of\ -mass energy of 7 TeV with the CMS detector at the LHC. Data corresponding to an integrated luminosity of 36 $pb^{-1}$ have been analysed. A n...

description The integrated and differential cross sections of the production of pairs of isolated photons have been measured in proton-proton collisions at a center-of\ -mass energy of 7 TeV with the CMS detector at the LHC. Data corresponding to an integrated luminosity of 36 $pb^{-1}$ have been analysed. A next-to-leadi\ ng-order perturbative QCD calculation is compared to the measurements and shows an overall satisfactory agreement. A discrepancy is observed in the regions\ of phase space populated by photons radiated at relatively small angles.
