"Table 12" of "Comparison of the Z/gamma*+jets to gamma+jets cross sections in pp collisions at sqrt(s)= 8 TeV"

CERN-LHC. A comparison of the differential cross sections for the processes $Z/\gamma^{*}+\text{jets}$ and photon $(\gamma)+\text{jets}$ is presented. The measurements are based on data collected with the CMS detector at $\sqrt{s}=8$\TeV corresponding to an integrated luminosity of 19.7\fbinv. The differential cross sections and their ratios are presented as functions of \pt. The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained as functions of the ratio of the $Z/\gamma^{*}$ \pt to the sum of all jet transverse momenta and of the ratio of the $Z/\gamma^{*}$ \pt to the leading jet transverse momentum. The data are corrected for detector effects and are compared to simulations based on several QCD calculations. For $Z/\gamma^{*}$ plus jets events we select: - two same flavour opposite sign leptons with $p_{T} > 20$ GeV and $|\eta| < 2.4$ and $71 < M_{\ell\ell} < 111 $ GeV and $p_{T}^{\ell\ell} > 100$ GeV - leptons are "dressed" with all photons in a cone of radius $\Delta R = 0.1$ - at least one jet, jet selection $p_{T} > 30$ GeV and $|\eta| < 2.4$, we remove jets within a radius of $\Delta R < 0.5$ with respect to the axes of each lepton - for the ratio plots a cut on Z rapidity |y|<1.4 is also applied For $\gamma$ plus jets events we select: - at least a prompt photon with $p_{T} > 100$ GeV and $|\eta| < 1.4$ (in case there is more than one photon the leading one satisfying all cuts is used) - the photon must be isolated, i.e. the scalar sum of the $p_T$ of all stable particle in a cone of radius $\Delta R = 0.4$ is less then 5 GeV - at least one jet, jet selection $p_{T} > 30$ GeV and $|\eta| < 2.4$ , we remove jets within a radius of $\Delta R < 0.5$ with respect to the axis of the photon.
