Descripción
The Poster presents the photon part of the Z/g cross section ratio, as well as the ratio itself. The Z/g cross section ratio is not only a precise measurements that probes the strenght of the perturbative corrections, and the pdf composition, but also a test to validate with CMS-collected data a commonly used method to estimate backgrounds raising from Z to invisibles decays in BSM searches. The photon part of the analysis includes also the photon pT-differential cross section ratio between N+1/N jets (N=1,2). The analyzed dataset corresponds to the full 2012 LHC run luminosity at 8 TeV collected by the CMS detector ($19.7fb^{-1}$), and results are compared to theoretical predictions.
