The CMS collaboration has performed a set of differential W +jets cross-section measurements with 2.2 fb −1 of Run 2 **data** -the first such measurements to be performed with a √ s = 13 TeV dataset [9]. The analysis strategy targeted events with a single, isolated, high-p T muon and considered jet multiplicities up to N jets = 6. Differential results unfolded to stable particle level were presented as a function of a number of kinematic observables including: the transverse momentum and absolute rapidity of the i th leading jet; the azimuthal separation between the i th leading jet and the selected reconstructed muon 2 ; the jet multiplicity; the scalar p T sum of reconstructed jets (H T ); and the separation in η-φ space between the reconstructed muon and its closest reconstructed jet. The final results as a function of H T for the N jets ≥ 1 case can be seen in Figure 2a. The measurements from **data** were compared to the predictions from a variety of simulated datasets. In all cases the results for the angular observables were found to be well described. Disagreements were observed between the **data** and a leading-order (LO) MG_aMC@NLO prediction, which underestimates the measured **data** at low H T , as well as at low to moderate jet p T .
