Measurement of cross section times branching ratio for W boson + photon and Z boson + photon and search for anomalous W boson-photon and Z boson-photon couplings at 1.8 TeV
… ratios. An analysis designed to search for anomalous couplings between the gauge bosons was also carried out using these results. Assuming only one anomalous coupling to be non-zero at a time, the 95% CL limits on $W\gamma$ anomalous couplings are, $-3.7 < \Delta\kappa\ < 3.7, -1.2 < \lambda …

A measurement of W boson-photon and Z boson-photon cross sections in the muon channel in 1.8 TeV proton-antiproton collisions
… on the Standard Model, and are sensitive to anomalous couplings of the W and Z bosons. Using the $W\sb{\gamma}$ and $Z\sb{\gamma}$ absolute cross section measurements, the absence of an excess of hard photons accompanying W and Z boson production enables us to obtain direct limites on …

Effective field theory of the electroweak sector
… It has many advantages over the traditional anomalous couplings framework. In particular, gauge invariance makes possible the calculation of loop corrections. Furthermore, the issue of unitarity violation is shown to be irrelevant in an effective field theory. There are nine dimension-six …

New physics searches in the ZZ sector with the ATLAS experiment
… thesis investigates the prospects of measuring anomalous triple gauge boson couplings in the ATLAS detector at the Large Hadron Collider (LHC). The most general (V ZZ, V = Z, g) vertex is parametrised by four couplings, fV = Z,g i=4,5 , all of which are zero in the Standard Model. Non-zero …
