This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This Letter describes the current most precise measurement of the WZ production cross section as well as limits on anomalous WWZ couplings at a center-of-mass energy of 1.96 TeV in proton-antiproton collisions. The WZ candidates are reconstructed from decays containing three charged leptons and missing energy from a neutrino, where the charged leptons are either electrons or muons. Using data collected by the CDF II detector (7.1 fb−1 of integrated luminosity), 64 candidate events are observed with the expected background contributing 8 ± 1 events. The measured total cross section?(p{bar p} → WZ) = 3.93{sub -0.53}{sup +0.60}(stat){sub -0.46}{sup +0.59}(syst) pb is in good agreement with the standard model prediction of 3.50 ± 0.21. The same sample is used to set limits on anomalous WWZ couplings.

Book excerpt: Direct measurements of the trilinear gauge boson couplings by the D0 collaboration at Fermilab are reported. Limits on the anomalous couplings were obtained at a 95% CL from four diboson production processes: W[gamma] production with the W boson decaying to e[nu] or[mu][nu], WW production with both of the W bosons decaying to e[nu] or[mu][nu], WW/WZ production with one W boson decaying to e[nu] and the other W or Z boson decaying to two jets, and Z[gamma] production with the Z boson decaying to ee, [mu][mu], or[nu][nu]. Limits were also obtained from a combined fit to W[gamma], WW[yields] dileptons and WW/WZ[yields] e[nu]jj data samples.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements are presented of $ \mathrm{ W \gamma\gamma } $ and $ \mathrm{ Z \gamma\gamma } $ production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb$^{-1}$ collected with the CMS detector at a center-of-mass energy of 8 TeV. Signal is identified through the $\mathrm{ W } \to \ell\nu$ and $\mathrm{ Z }\to\ell\ell$ decay modes, where $\ell$ is a muon or an electron. The production of $ \mathrm{ W \gamma\gamma } $ and $ \mathrm{ Z \gamma\gamma } $, measured with significances of 2.6 and 5.9 standard deviations, respectively, is consistent with standard model predictions. In addition, limits on anomalous quartic gauge couplings in $ \mathrm{ W \gamma\gamma } $ production are determined in the context of a dimension-8 effective field theory.

Available in PDF, EPUB and Kindle. Book excerpt: This study presents measurements of W±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 ?W±Z→l'?ll = 35.1 ± 0.9(stat) ± 0.8(sys) ± 0.8(lumi) fb, for one leptonic decay channel. In comparison, the next-to-leading-order Standard Model expectation is 30.0 ± 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±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±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 ± 0.01 fb. Limits on anomalous quartic gauge boson couplings are also extracted.

Book excerpt: In this thesis, the first measurement of Z(vv̄)[photon] cross section in pp collisions at [square root of]s = 7 TeV has been done using data collected by the CMS detector. The measured cross section is 21.3 ± 4.2 (stat.) ± 4.3 (syst.) ± 0.5 (lumi.) fb. This measurement is based on the observations of events with missing transverse energy in excess of 130 GeV and photon in the rapidity range [eta]

Book excerpt: Recent trilinear gauge boson couplings measurements by the CDF and D0 Collaborations at the Fermilab Tevatron are presented. The measurements were done by analyzing diboson production in multiple decay channels and final states. No deviations from the Standard Model description of the WWZ, WW[gamma], ZZ[gamma] and Z[gamma][gamma] vertices were found. Limits on anomalous gauge couplings set by these analyses are the tightest available to date.
