Measuring the anomalous quartic gauge couplings in the W+W? ? W+W? process at muon collider using artificial neural networks

The WW cross-section and triple gauge couplings at OPAL

A study of W-pair production in ee collisions at LEP energies up to 183 GeV is presented [1]. Using all decay channels, the total WW cross-section is measured to 15:43 0:61(stat:) 0:26(syst:)pb. The W-branching fraction into hadrons of 67:9 1:2(stat:) 0:5(syst:)% is interpreted as a measurement of the CKM matrix element jVcsj. The angular distributions of the selected W's and their decay produc...

Quartic Gauge Boson Couplings at Linear Colliders | Interplay of Wwz=zzz Production and Ww-fusion |

We study new physics eeects to the quartic gauge boson couplings formulated by the electroweak chiral Lagrangian. Five next-to-leading order operators characterize the anomalous quartic gauge interactions which involve pure Goldstone boson dynamics for the electroweak symmetry breaking. We estimate the typical size of these couplings in diierent strongly-interacting models and examine the sensi...

Probing Anomalous WW γ and WWZ Couplings with Polarized Electron Beam at the LHeC and FCC-Ep Collider

Abstract—We study the anomalous WW and WWZ couplings by calculating total cross sections of two processes at the LHeC with electron beam energy Ee=140 GeV and the proton beam energy Ep=7 TeV, and at the FCC-ep collider with the polarized electron beam energy Ee=80 GeV and the proton beam energy Ep=50 TeV. At the LHeC with electron beam polarization, we obtain the results for the difference of ...

Anomalous triple and quartic gauge boson couplings

This article reviews some recent developments in the analysis of anomalous triple and quartic vector boson couplings that have been discussed at the UK Phenomenology Workshop on Collider Physics 1999 in Durham.
