Abstract

We have investigated the anomalous quartic couplings defined by the dimension-8 operators in semileptonic decay channel of the e+eνeWW+νˉee^{+}e^{-}\rightarrow \nu_{e} W^{-} W^{+} \bar{\nu}_{e} process for unpolarized and polarized electron (positron) beam at the Compact Linear Collider. We give the 95%95\% confidence level bounds on anomalous fS0Λ4\frac{f_{S0}}{\Lambda^{4}}, fS1Λ4\frac{f_{S1}}{\Lambda^{4}} and fT0Λ4\frac{f_{T0}}{\Lambda^{4}} couplings for various values of the integrated luminosities and center-of-mass energies. The best sensitivities obtained on anomalous fS0Λ4\frac{f_{S0}}{\Lambda^{4}}, fS1Λ4\frac{f_{S1}}{\Lambda^{4}} and fT0Λ4\frac{f_{T0}}{\Lambda^{4}} couplings through the process e+eνeWW+νˉee^{+}e^{-}\rightarrow \nu_{e} W^{-} W^{+} \bar{\nu}_{e} with beam polarization at s=3\sqrt{s}=3 TeV and an integrated luminosity of Lint=2000L_{int}=2000 fb1^{-1} are [4.05;3.67]×1012[-4.05;\, 3.67]\times 10^{-12} GeV4^{-4}, [3.08;2.12]×1012[-3.08; \, 2.12]\times 10^{-12} GeV4^{-4}, [1.98;0.64]×1013[-1.98; \, 0.64]\times 10^{-13} GeV4^{-4}, which show improvement over the current bounds.
