Özet

We have investigated the anomalous quartic couplings defined by the dimension-8 operators in semileptonic decay channel of the e(+)e--> nu eW-W+(nu) over bar (e) process for unpolarized and polarized electron (positron) beam at the Compact Linear Collider. We give the 95% confidence level bounds on the anomalous f(S0)/Lambda(4), f(S1)/Lambda(4), and f(T0)/Lambda(4) couplings for various values of the integrated luminosities and center-of-mass energies. The best sensitivities obtained on anomalous f(S0)/Lambda(4), f(S1)/Lambda(4), and f(T0)/Lambda(4) couplings through the process e(+)e--> nu eW-W+(nu) over bar (e) with beam polarization at v(e) = 3TeV and an integrated luminosity of L-int = 2000fb(-1) are [-4.05; 3.67] x 10(-12) GeV-4, [-3.08;2.12] x 10(-12) GeV-4, and [-1.98;0.64] x 10(-13) GeV-4 , which show improvement over the current bounds.
