Description
This talk will present a measurement of the cross section of W boson pair production in photon fusion (γγ → WW), using an integrated luminosity of 138 fb^−1 of proton-proton collision data collected by the CMS experiment in 2016-2018 at a center-of-mass energy of √s = 13 TeV. Events are selected in the final state with one electron, one muon, and a low multiplicity of tracks associated with the electron-muon production vertex. The total cross section of the γγ → WW production is measured to be 643+82 −78 fb, and a fiducial cross section of 3.96 + 0.53-0.51 fb is measured in a phase space defined with selection criteria close to those of the analysis. In addition, constraints on dimension-8 operators from an effective field theory framework are set.
