Description
This talk presents an observation of the photon-fusion production of W boson pairs using the CMS detector at the LHC. The total cross section of the $W^+W^-$ production in photon fusion is measured using proton-proton collision data with an integrated luminosity of 138$f^{-1}$ collected with the CMS detector in 2016--2018 at a center-of-mass energy of $\sqrt{s}$=13 TeV and is in agreement with the prediction of SM. This agreement enables stringent constraints on anomalous quartic gauge couplings within a dimension-8 effective field theory framework.
