چکیده
We have estimated the sensitivity to anomalous couplings of $\gamma\gamma\gamma Z$ vertex in $\gamma\gamma\rightarrow\gamma scattering Compton backscattered photons at CLIC. Both polarized and unpolarized collisions $e^+e^-$ energies 1500 GeV 3000 are addressed, contributions helicity amplitudes derived. The differential total cross sections calculated. obtained 95\% C.L. exclusion limits on quartic gauge (QGCs). They compared with corresponding bounds derived for via $\gamma production LHC. constraints QGCs one two orders magnitude more stringent that HL-LHC. partial-wave unitarity examined. It is shown not violated region studied paper.

The processes γγ → γγ , γZ , ZZ
The Standard Model contributions to the processes γγ → γγ, γZ and ZZ at sufficiently high energies, are found to be helicity conserving and almost purely imaginary. This is due to the W-loop contribution, which is much bigger than the fermionic ones at such energies. Thus the structure of these amplitudes acquires an impressive simplicity at high energies. Nothing like this appears in other pro...
متن کاملQuartic Anomalous Couplings in γγ Colliders
We study the constraints on the vertices W+W−Zγ, W+W−γγ, and ZZγγ that can be obtained from triple-gauge-boson production at the next generation of linear e+e− colliders operating in the γγ mode. We analyze the processes γγ → W+W−V (V = Z, or γ) and show that these reactions increase the potential of e+e− machines to search for anomalous four-gaugeboson interactions.

متن کاملFour-fermion production at γγ colliders: 1. Lowest-order predictions and anomalous couplings
We have constructed a Monte Carlo generator for lowest-order predictions for the processes γγ → 4f and γγ → 4fγ in the Standard Model and extensions thereof by an effective γγH coupling as well as anomalous triple and quartic gauge-boson couplings. Polarization is fully supported, and a realistic photon beam spectrum can be taken into account. For the processes γγ → 4f all helicity amplitudes a...
متن کاملAnalyzing the anomalous dipole moment type couplings of heavy quarks with FCNC interactions at the CLIC
A. T. Tasci, A. Senol, and C. Verep Department of Physics, Kastamonu University, 37100, Kastamonu, Turkey Abstract In this study we examine both anomalous magnetic and dipole moment type couplings of a heavy quark via its single production with subsequent dominant Standard Model decay modes at the Compact Linear Collider (CLIC). The signal and background cross sections are analyzed for heavy qu...
متن کاملVector Boson Pair Production in Hadronic Collisions at O(αs): Lepton Correlations and Anomalous Couplings
We present cross sections for production of electroweak vector boson pairs, WW , WZ and ZZ, in pp̄ and pp collisions, at next-to-leading order in αs. We treat the leptonic decays of the bosons in the narrow-width approximation, but retain all spin information via decay angle correlations. We also include the effects of WWZ and WWγ anomalous couplings. Submitted to Physical Review D
