Descripción
We present a measurement of the differential vector boson transverse momentum cross-section of Z plus jets in proton-proton collisions. The data are collected with the CMS detector at $\sqrt{s}=8\,\mathrm{TeV}$, corresponding to an integrated luminosity of $19\,\mathrm{fb}^{-1}$. It is shown that the precise measurement allows for stringent test of (high multiplicity) NLO perturbative QCD calculations from BlackHat and other multi purpose Monte Carlo generators in several phasespace selection. In addition we confront theoretical predictions with data for differential Z cross-section ratios between jet multiplicities and differential cross-section of ratios between the transverse Z momentum and hadronic quantities like Zpt/HT.
