【 摘 要 】

Diboson production in proton–proton collisions presents an opportunity to study the self-interaction between gauge bosons via anomalous trilinear gauge couplings (aTGC). The values of these couplings are fully fixed in the SM by the gauge structure. Thus, any deviation of the observed strength of the TGC from the SM prediction would indicate new physics. This paper presents the limits on anomalous 𝑊𝑊𝛾, 𝑍𝑍𝛾 and 𝑍𝛾 𝛾 trilinear gauge couplings in proton–proton collisions at the centre of mass energy of 7 TeV with the CMS detector.
