Triboson measurements, VV scattering and quartic gauge couplings with ATLAS and CMS

We present measurements of triboson production and vector boson scattering in pp collisions at 7 and 8 TeV in the center-of-mass energy based on data recorded by the ATLAS and CMS detectors at the LHC in 2011 and 2012. The results are also interpreted in terms of constraints on anomalous quartic gauge couplings. In addition, we present studies of exclusive and quasi-exclusive $\gamma\gamma\rightarrow W^+W^-$ production p-p collisions at the LHC using the CMS detector, and new limits on anomalous quartic couplings.
