Abstract Searching for deviations in quartic gauge boson couplings (QGCs) is one of the main goals of the electroweak program at the LHC. We consider positivity bounds adapted to the Standard Model. and show that a set of positivity constraints on 18 anomalous QGC couplings can be derived. by requiring that the vector boson scattering amplitudes of specific channels and polarisations ... https://www.sukrensi.com/
