Book Description
A measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton–proton collisions at √s = 8 TeV are presented. The analysis is based on a data sample, corresponding to an integrated luminosity of 19.6 fb−1, collected with the CMS experiment at the LHC. The measurements are performed in the leptonic decay modes ZZ → lll'l', where l = e,? and l' = e,?,?. The measured total cross section ?(pp → ZZ) = 7.7 ± 0.5 (stat)-0.4+0.5 (syst) ± 0.4 (theo) ± 0.2 (lumi) pb, for both Z bosons produced in the mass range 60 msubZ/sub 120 GeV, is consistent with standard model predictions. Differential cross sections are measured and well described by the theoretical predictions. As a result, the invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ? couplings at the 95% confidence level: –0.004 fsub4/subsupZ/sup 0.004, –0.004 fsub5/subsupZ/sup 0.004, –0.005 fsub4

Book Description
Studies of four-lepton production in proton-proton collisions, pp → (Z/[gamma]*)(Z/[gamma]*)→ 4l, where l = e or [mu], using data collected during 2016-2018 (Run II) are presented. The dataset corresponds to an integrated luminosity of 137 fb^(−1) at a center-of-mass energy of 13 TeV, collected by the CMS detector at the LHC. All reported measurements use the 2l2l' final states, where l,l' = e or [mu]. The total ZZ cross section for all events with two Z bosons in the mass range 60-120 GeV is measured and found to be [sigma](pp → ZZ) = 17.2 ± 0.3 (stat) ± 0.5 (syst) ± 0.4 (theo) ± 0.3 (lumi) pb. Differentialcross sections are measured as functions of a number of kinematic observables. Allthese results agree with standard model predictions. Searches for anomalous triplegauge couplings are performed, and the four-lepton invariant mass distributions areused to set the most stringent limits to date on a number of parameters affectingneutral gauge boson interactionsl

Book Description
I present a measurement of the W±Z production cross section in the leptonic final states in pp collisions at √s = 7 TeV and limits on anomalous trilinear gauge couplings, using 4.64 fb-1 of data collected using the ATLAS experiment at the LHC. The production cross section has been determined to be 19.0+1.4-1.3(stat.)±0.9(syst.)±0.4(lumi.) pb, in agreement with the Standard Model (SM) expectation of 17.6+1.1-1.0 pb. A search for anomalous trilinear gauge couplings has been conducted and limits have been set at the 95% confidence level; the result is consistent with the SM couplings.
