Özet
0.45, is 17.2±0.2(stat)±1.9(syst)±0.4(lumi)pb. Differential cross sections are measured as a function of the diphoton invariant mass, the diphoton transverse momentum, the azimuthal angle difference between the two photons, and the cosine of the polar angle in the Collins–Soper reference frame of the diphoton system. The results are compared to theoretical predictions at leading, next-to-leading, and next-to-next-to-leading order in quantum chromodynamics. © 2014, CERN for the benefit of the CMS collaboration.
