Beam energies: (4000.0, 4000.0) GeV Run details:
This paper presents measurements of $W^\pm Z$ production in pp collisions at a center-of-mass energy of 8 TeV. The gauge bosons are reconstructed using their leptonic decay modes into electrons and muons. The data were collected in 2012 by the ATLAS experiment at the Large Hadron Collider and correspond to an integrated luminosity of 20.3 fb${}^{-1}$. The measured inclusive cross section in the detector fiducial region is $\sigma(W^\pm Z\to \ell^\prime\nu\ell\ell) = 35.1\pm 0.9$(stat)$\pm 0.8$(sys)$\pm 0.8$(lumi) fb, for one leptonic decay channel. In comparison, the next-to-leading-order Standard Model expectation is $30.0\pm 2.1$ fb. Cross sections for $W^+ Z$ and $W^- Z$ production and their ratio are presented as well as differential cross sections for several kinematic observables. Limits on anomalous triple gauge boson couplings are derived from the transverse mass spectrum of the $W^\pm Z$ system. From the analysis of events with a $W$ and a $Z$ boson associated with two or more forward jets an upper limit at 95% confidence level on the $W^\pm Z$ scattering cross section of 0.63 fb, for each leptonic decay channel, is established, while the Standard Model prediction at next-to-leading order is $0.13\pm 0.01$ fb. Limits on anomalous quartic gauge boson couplings are also extracted. For distributions that include the infinity symbol ($\infty$) on the horizontal axis, the last bin will include the events from the overflow bin. Users should note that explicit matching of lepton flavour between individual SM neutrinos and charged leptons is used in this analysis routine, to match the MC-based correction to the fiducial region applied in the paper. The data are therefore only valid under the assumption of the Standard Model and cannot be used for BSM reinterpretation. Source code: ATLAS_2016_I1426523.cc 1// -*- C++ -*-
