Probe of the anomalous quartic couplings with beam polarization at the CLIC

We have investigated the anomalous quartic couplings defined by the dimension-8 operators in semileptonic decay channel of the e→eW-W+e process for unpolarized and polarized electron (positron) beam at the Compact Linear Collider. We give the 95% confidence level bounds on the anomalous fS0/Λ4, fS1/Λ4, and fT0/Λ4 couplings for various values of the integrated luminosities and center-of-mass energies. The best sensitivities obtained on anomalous fS0/Λ4, fS1/Λ4, and fT0/Λ4 couplings through the process e→eW-W+e with beam polarization at s=3 TeV and an integrated luminosity of Lint=2000 fb-1 are [-4.05;3.67]×10-12 GeV-4, [-3.08;2.12]×10-12 GeV-4, and [-1.98;0.64]×10-13 GeV-4, which show improvement over the current bounds.
