Search for anomalous quartic $WWZ\gamma$ couplings at the future linear $e^{+}{e}^{-}$ collider

Abstract

In this paper, the potentials of two different processes $e^{+}{e}^{-}\to W^{-}{W}^{+}\gamma$ and $e^{+}{e}^{-}\to e^{+}{\gamma }^{\ast }{e}^{-}\to e^{+}{W}^{-}Z{\nu }_e$ at the Compact Linear Collider (CLIC) are examined to probe the anomalous quartic $WWZ\gamma$ gauge couplings. For $\sqrt{s}=0.5,1.5$ and 3 TeV energies at the CLIC, $95\%$ confidence level limits on the anomalous coupling parameters defining the dimension-six operators are found via the effective Lagrangian approach in a model independent way. The best limits on the anomalous couplings $\frac{k_0^W}{{\Lambda }^2}$, $\frac{k_c^W}{{\Lambda }^2}$, $\frac{k_2^m}{{\Lambda }^2}$ and $\frac{a_n}{{\Lambda }^2}$ which can be achieved with the integrated luminosity of $L_{int}=590$ fb${}^{-1}$ at the CLIC with $\sqrt{s}=3$ TeV are $[-8.80;8.73]\times 10^{-8}$ GeV${}^{-2}$, $[-1.53;1.51]\times 10^{-7}$ GeV${}^{-2}$, $[-3.75;3.74]\times 10^{-7}$ GeV${}^{-2}$ and $[-9.13;9.09]\times 10^{-7}$ GeV${}^{-2}$, respectively.
