Description
A measurement of the cross section of W boson pair production in photon fusion (γγ → WW) is presented, using an integrated luminosity of 138 fb^−1 of protonproton collision data collected 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 659+82 −78 fb, and a fiducial cross section of 4.1 ± 0.5 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.
