“…Since future lepton colliders will have a cleaner environment than hadron colliders, a less systematic uncertainty can be taken into account when obtaining limits on the anomalous quartic couplings. However, there are also phenomenological studies in the literature for the CLIC that consider values for the systematic uncertainties of 3% and 5% [42,43]. Taking these studies into account, we obtain limits on the anomalous quartic couplings by the systematic uncertainties of 3%-5%.…”

The spontaneous breaking of the $SU(2)_{L}\times U(1)_{Y}$ electroweak symmetry of the Standard Model (SM) sets the constraints on triple and quartic gauge couplings. Therefore, the measurement of multiboson production in $e^{-} e^{+}$ collisions allows us to directly test the predictions of the SM and to indirectly probe new physics beyond the SM. In this paper, we focus on the process $e^{-} e^{+} \to e^{-} Z\gamma e^{+}$ with $Z$ boson decaying into neutrinos to study the anomalous quartic gauge couplings using the effective Lagrangian approach at the Compact Linear Collider (CLIC). We obtain the sensitivities on the anomalous $ f_ {T,i}/\Lambda^4$ ($i=0,2,5,6,7,8,9$) couplings taking into account the systematic uncertainties of $3, 5 \%$ at $95\%$ Confidence Level for the CLIC with $\sqrt{s}=3$ TeV. Our results show that the sensitivities on some anomalous couplings without systematic errors are up to two orders of magnitude better than the current experimental limits. Considering a realistic systematic uncertainty such as $5 \%$ from possible experimental sources, the sensitivity of all anomalous quartic couplings becomes worse by about $10\%$ compared to those without systematic uncertainty for the CLIC.

The non-Abelian nature of the Standard Model (SM) entails the existence of the gauge bosons' self-interactions. The gauge bosons' self-interactions are important to test the SM and see the new physics effects. These effects can be analyzed in the effective theory approach which is the main aim of this study. We examine the ZZZ and ZZγ anomalous neutral triple gauge couplings (aNTGC) via the process e^- e^+→ZZ with both unpolarized and polarized electron beam with the √s=3 TeV at CLIC. In the final state, semi-leptonic decay of Z-bosons (Z→jj , Z→ν_l (ν_l ) ̅ ) are considered. We focused on CP-violating C_BB/Λ^4 , C_BW/Λ^4 , C_WW/Λ^4 and CP-conserving C_(B ̅W)/Λ^4 couplings. The sensitivities are obtained at 95% Confidence Level with luminosities of L_int=5 ab-1, L_int=1 ab-1 and L_int=4 ab-1 for unpolarized, 80% and -80% polarized electron beams, respectively. Obtained sensitivities on anomalous couplings are 3-20 times stringent than the current experimental limits and comparable with the related phenomenological studies in the literature.
