Recent measurements of Vector Boson Scattering at CMS

by Aram Apyan (Fermi National Accelerator Laboratory)

US/Eastern
Description

The observation of a Higgs boson at the LHC in 2012 presents a new paradigm of precision physics aiming at the investigation of the Electroweak (EW) symmetry breaking. The study of VBS processes provides key insight into the Higgs sector as well as the self-interactions of W and Z bosons through triple and quartic gauge couplings.  I will show the first observation of the EW WZ production with the CMS detector along with the first detailed characterization of the same-sign EW WW production. The most stringent constraints on the structure of quartic vector boson interactions in the framework of dimension-8 effective field theory operators are reported.  The scattering of longitudinally polarized W and Z bosons is a particularly interesting probe of the SM, as its tree-level amplitudes would violate unitarity at high energies without delicate cancellations from quartic gauge couplings and Higgs-boson contributions. I will show the first measurement of the scattering of polarized same-sign W boson pairs
