Abstract
A comparison of the differential cross sections for the processes Z/γ[superscript *] + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at √s=8 TeV. corresponding to an integrated luminosity of 19.7 fb[superscript −1]. The differential cross sections and their ratios are presented as functions of p T . The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained as functions of the ratio of the Z/γ[superscript *] p[subscript T] to the sum of all jet transverse momenta and of the ratio of the Z/γ[superscript *] p[subscript T] to the leading jet transverse momentum. The data are corrected for detector effects and are compared to simulations based on several QCD calculations.Keywords: Jets, Hadron-Hadron, Scattering Beyond Standard Model, QCD, Photon production
