Measurement of the production cross section for pairs of isolated photons in pp collisions at √s = 7 TeV

ArticleAçık Erişim

Özet

Abstract: The integrated and differential cross sections for the production of pairs of isolated photons is measured in proton-proton collisions at a centre-of-mass energy of 7TeV with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 36 pb-1 is analysed. A next-to-leading-order perturbative QCD calculation is compared to the measurements. A discrepancy is observed for regions of the phase space where the two photons have an azimuthal angle difference Δ ℓ ≲. 2:8 rad. © SISSA 2012.
