The production of electroweak bosons is an important part the Standard Model and it can also shed a light on new physics, in the form of anomalous gauge couplings. This poster presents the study of exclusive or quasi-exclusive γ γ → W +W − production. The measurement of the process pp → p(∗) +W+W− + p(∗) → p(∗) +e±μ∓ + p(∗) used an integrated luminosity of 19.7fb−1 of 8TeV proton-proton collisions at the LHC. Events are selected by requiring the presence of an electron-muon pair with large transverse momentum pT(μ±e∓) > 30GeV, and no associated charged particles detected from the same vertex. With this analysis the CMS Collaboration has set upper limits on the values of anomalous quartic gauge coupling coefficients for both dimension-6 and dimension-8 effective field theory operators, giving the most stringent limits to date.
