Anomalous quartic WW λ λ and ZZλ λ couplings in γp collision at the LHC

Abstract

We analyze the anomalous quartic gauge boson couplings WW λ λand ZZ, λ λ described by dimension-six effective quartic Lagrangian at the LHC. The sensitivities to anomalous quartic gauge couplings aW,Z 0,c /δ2 by examining the two different photon-induced processes pp → pγp → pWqX and pγp → pp → pZZqX with W and Z's decaying leptonically are investigated. We show that p mode of photon-induced reactions at the LHC are able to probe these couplings to the order of 10-6-10-7 GeV-2 at 95% confidence level (C.L.) with √s = 14 TeV and for proton-proton luminosities in the range of 30-200 fb-1.
