Anomalous Couplings in the $e^{+}e^{-} \to ZZ$ Process
We discuss experimental aspects related to the possible existence of anomalous ZZV couplings (V=Z,gamma) in the ee->ZZ process. We find that, among several options, the optimal procedure to quantify their presence requires the inclusion of anomalous couplings in a complete four-fermion final-stat...

| description | We discuss experimental aspects related to the possible existence of anomalous ZZV couplings (V=Z,gamma) in the ee->ZZ process. We find that, among several options, the optimal procedure to quantify their presence requires the inclusion of anomalous couplings in a complete four-fermion final-state generator. Various comparisons and checks proof the correctness of our calculations at the percent level. |

We find that, among several options, the optimal procedure to quantify their presence requires the inclusion of anomalous couplings in a complete four-fermion final-state generator. Various comparisons and checks proof the correctness of our calculations at the percent level.We discuss experimental aspects related to the $\mathrm{e^+ e^-} \to \mathrm{Z}\mathrm{Z}$ process and to the search for anomalous ZZV couplings (V$= \mathrm{Z}, \gamma$) at LEP2 and future $\mathrm{e^+ e^-}$ colliders. We present two possible approaches for a realistic study of the reaction and discuss the differences between them. We find that the optimal method to study double Z resonant production and to quantify the presence of anomalous couplings requires the use of a complete four-fermion final-state calculation.hep-ph/9812435CIEMAT-870CIEMAT-870oai:cds.cern.ch:3748482000 |
