| Abstract: Measurements of the differential cross sections of Z+jets, $\gamma$+jets, and their ratio, are presented as a function of the boson transverse momentum. Measurements are also presented of the Z boson angular distribution in events where the Z boson is emitted collinear to a jet with very high transverse momentum. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb$^{-1}$ recorded by the CMS experiment at the LHC. The data are compared to different theoretical predictions after correcting for detector effects and show varying levels of agreement. In general, the predictions at higher orders in perturbation theory show better agreement with the data. | ||
