Özet
We carry out a study in the approach of a dimension-eight effective field theory on the anomalous quartic WW gamma gamma couplings that arise from the process pp -> WW gamma gamma at the Future Circular Collider-hadron hadron (FCC-hh). The process is sensitive to the WW gamma gamma vertex, and future projections on the anomalous f(M,i)/Lambda(4) and f(T,j)/Lambda(4) couplings can be put by measurements of WW gamma gamma production. We illustrate the physics opportunities and reach of the FCC-hh operating for a high integrated luminosity scenario of L = 1,5, 10, 30 ab(-1) of proton-proton collisions at a center-of-mass energy of root s = 100 TeV and systematic uncertainties of delta(sys) = 0%, 3%, 5%, 10%. Production cross-sections of the signal and the sensitivity constraints on the anomalous f(M ,i)/Lambda(4) and f(T ,j)/Lambda(4)couplings at 95% C.L. are identified through the leptonic and hadronic decay modes of the W-boson. The FCC-hh sensitivity on these anomalous couplings is expected might reach up to the order of magnitude O(10(-4) - 10(1)). These sensitivity perspectives indicate that the pp -> WW gamma gamma channel at the FCC-hh has a greater potential to search for the anomalous quartic WW gamma gamma couplings and to search for new physics than present colliders.
