Abstract
Precision measurements of multiboson production are a validation of the Standard Model. These multiboson processes are a background to Higgs boson measurements and searches for Beyond the Standard Model physics. In this contribution, we presented recent measurements of multiboson final states performed in CMS, involving W, Z and photon combinations. Inclusive and differential cross sections were compared to different theoretical predictions. Phase space regions that provide sensitivity to anomalous triple or quartic gauge couplings were also shown. These coupling strengths are directly related to the broken electroweak symmetry and deviations from the SM are a clear signal of new physics.
