Abstract
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 next-to-leading order perturbative QCD calculation and two generators that combine tree-level matrix element calculations with parton showers.
