| Abstract | The study of vector boson (V = W, Z) polarization in diboson production serves as an important test of electroweak symmetry breaking mechanism and can be used as a tool to search for new physics effects. This is also a first step to studying longitudinal polarization in the rare process of vector boson scattering. In this talk, we present recent measurements of polarization observables in VV production using data collected by the CMS detector at the LHC. The analyses explore angular distributions and polarization fractions of the W and Z bosons in final states with leptons and missing transverse energy. We discuss the techniques used to extract polarization information and compare the results with theoretical predictions from the Standard Model. |
