Study of anomalous ZZy and Zyy couplings at LEP

We search for anomalous ZZy and Zyy couplings with the L3 detector at LEP. The analysis is based on the study of the process e+e+→Zy at center-of-mass energies in the range 161 GeV <√s< 183 GeV. No evidence for anomalous effects is found. Limits at the 95% confidence level are set on the value...

Descrição
Resumo:We search for anomalous ZZy and Zyy couplings with the L3 detector at LEP. The analysis is based on the study of the process e+e+→Zy at center-of-mass energies in the range 161 GeV <√s< 183 GeV. No evidence for anomalous effects is found. Limits at the 95% confidence level are set on the values of the eight possible anomalous couplings. Depending on the type of coupling new physics scales below 213 GeV to 1083 GeV are excluded.
