"Rapidity distributions in exclusive Z+jet and γ+jet events in pp collisions at √s=7  TeV." <i>Physical Review D,</i> 88, no. 11 (2013) American Physical Society: 112009. http://dx.doi.org/10.1103/PhysRevD.88.112009.https://hdl.handle.net/1911/81613Rapidity distributions are presented for events containing either a Z boson or a photon with a single jet in proton-proton collisions produced at the CERN LHC. The data, collected with the CMS detector at √s=7  TeV, correspond to an integrated luminosity of 5.0  fb−1. The individual rapidity distributions of the boson and the jet are consistent within 5% with expectations from perturbative QCD. However, QCD predictions for the sum and the difference in rapidities of the two final-state objects show discrepancies with CMS data. In particular, next-to-leading-order QCD calculations, and two common Monte Carlo event generators using different methods to match matrix-element partons with parton showers, appear inconsistent with the data as well as with each other.engThis is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Journal articlehttp://dx.doi.org/10.1103/PhysRevD.88.112009
