# Probing triple-W production and anomalous WWWW coupling at the CERN LHC and future $$\mathcal{O}(100)$$ TeV proton-proton collider

Journal of High Energy Physics, Mar 2015

Triple gauge boson production at the LHC can be used to test the robustness of the Standard Model and provide useful information for VBF di-boson scattering measurement. Especially, any derivations from SM prediction will indicate possible new physics. In this paper we present a detailed Monte Carlo study on measuring W ± W ± W ∓ production in pure leptonic and semileptonic decays, and probing anomalous quartic gauge WWWW couplings at the CERN LHC and future hadron collider, with parton shower and detector simulation effects taken into account. Apart from cut-based method, multivariate boosted decision tree method has been exploited for possible improvement. For the leptonic decay channel, our results show that at the $$\sqrt{s}=8(14)\left[100\right]$$ TeV pp collider with integrated luminosity of 20(100)[3000] fb−1, one can reach a significance of 0.4(1.2)[10]σ to observe the SM W ± W ± W ∓ production. For the semileptonic decay channel, one can have 0.5(2)[14]σ to observe the SM W ± W ± W ∓ production. We also give constraints on relevant Dim-8 anomalous WWWW coupling parameters.
