Quartic anomalous couplings at LEP
The search for quartic anomalous gauge couplings at LEP requires appropriate predictions for the radiative processes ee → νν̄γγ, ee → qq̄γγ and ee → 4 fermions+γ. Matrix elements are exactly computed at the tree level, and the effects of anomalous couplings and initial-state radiation are included. Comparisons with results and approximations existing in the literature are shown and commented. Imp...
متن کاملQuartic Anomalous Couplings in eγ Colliders
We study the production of gauge boson pairs at the next generation of linear e+e− colliders operating in the eγ mode. The processes eγ → V V F (V, V ′ = W , Z, or γ and F = e or ν) can give valuable information on possible deviations of the quartic vector boson couplings from the Standard Model predictions. We establish the range of the new couplings that can be explored in these colliders bas...
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. Submitted to Physical Revie...
متن کاملAnomalous triple and quartic gauge boson couplings
This article reviews some recent developments in the analysis of anomalous triple and quartic vector boson couplings that have been discussed at the UK Phenomenology Workshop on Collider Physics 1999 in Durham.
متن کاملProbe 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 3TeV to investigate anomalous quarticWWZγ 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 luminosi...
