LHC as a Photon Collider, Results from Atlas (and CMS)”

Room: Sunrise - WH11NE Extensions of the Standard Model could create anomalous Quartic Couplings for gamma gamma W W. Limits on such effects were set by the LEP experiments and later by D0. The dominant constraints now come from the LHC experiments, where the Standard Model gamma gamma -> W W process is “seen.” We (ATLAS) also set a limit on diffractive Higgs production using H ->W W*.
