Probe of anomalous quartic WWZγ couplings in photon-photon collisions

In this paper, we examine the potentials of the processes γγ → W + W − Z and e + e − → e + γ * γ * e − → e + W + W − Ze − at the CLIC with s = 0 . 5, 1.5 and 3 TeV to investigate anomalous quartic WWZγ couplings by two different CP-violating and CP-conserving effective Lagrangians. We find 95% confidence level sensitivities on the anomalous coupling parameters at the three CLIC energies and various integrated luminosities. The best sensitivities obtained from the process γγ → W + W − Z on the anomalous k 0 W Λ 2 , k c W Λ 2 and k 2 m Λ 2 couplings defined by CP-conserving effective Lagrangians are [−1 . 73; 1 . 73]×10 −7 GeV −2 , [−2 . 44; 2 . 44]×10 −7 and [−1 . 89; 1 . 89]×10 −7 GeV −2 , while a n Λ 2 coupling determined by CP-violating effective Lagrangians is obtained as [−1 . 74; 1 . 74]×10 −7 GeV −2 . In addition, the best sensitivities derived on k 0 W Λ 2 , k c W Λ 2 and k 2 m Λ 2 and a n Λ 2 from the process e + e − → e + γ * γ * e − →  e + W + W − Ze − are obtained as [−1 . 09; 1 . 09]×10 −6 GeV −2 , [−1 . 54; 1 . 54]×10 −6 GeV −2 , [−1 . 18; 1 . 18]×10 −6 and [−1 . 04; 1 . 04]×10 −6 GeV −2 , respectively.
