Limits on anomalous trilinear gauge couplings at the CMS with 7TeV Large Hadron Collider data

摘要

Diboson production in protona€“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 e?‘?e?‘?e???, e?‘?e?‘?e??? and e?‘?e??? e??? trilinear gauge couplings in protona€“proton collisions at the centre of mass energy of 7 TeV with the CMS detector.
