Anomalous Quartic $WW\gamma \gamma$ and $ZZ\gamma \gamma$ Couplings in Two-Photon Processes at the LHC

Two-photon production of WW/ZZ pairs is used to calculate sensitivities to anomalous quartic couplings between photon and massive electroweak bosons at the LHC. We show how the signal can be selected from the diffractive and two-photon backgrounds and that the current sensitivities can be improved b...

description Two-photon production of WW/ZZ pairs is used to calculate sensitivities to anomalous quartic couplings between photon and massive electroweak bosons at the LHC. We show how the signal can be selected from the diffractive and two-photon backgrounds and that the current sensitivities can be improved by almost two orders of magnitude with early data. Using the full LHC luminosity and the forward detectors installed at 220m and 420m from the CMS or ATLAS detectors, sensitivities on anomalous couplings of the order of 10−6 GeV−2 can be achieved.
