摘要：
At the LEP 2 center-of-mass energies quartic gauge boson couplings (QGCs) involving at least one photon can be studied in final states with two W bosons and one photon, two acoplanar photons and two photons and a Z boson. Preliminary determinations of event rates and of distributions of kinematic variables, which are in good agreement with the Standard Model predictions, have been used to constrain the strength of anomalous contributions to quartic couplings of the gauge bosons.
