【 摘 要 】

The area-normalized angular distributions in events containing a $Z^{0}$ boson and a jet, using the electron decay mode, are presented. The data samples correspond to 5 fb−1 of proton–proton collisions at $sqrt{s}$ = 7 TeV, collected by the CMS detector. Events in which there is a 𝑍 boson and at least one jet, with a jet transverse momentum threshold of 30 GeV/c and absolute jet rapidity less than 2.4, are selected for this analysis. We compare our measurements with a nextto-leading order perturbative QCD calculation and two generators that combine tree-level matrix element calculations with parton showers.
