Production of single W bosons in e + e − interactions at 130≤s≤183 GeV and limits on anomalous WWγ couplings
1998
Abstract We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. The measured cross sections at five different centre-of-mass energies are consistent with the Standard Model expectations. The following limits on the anomalous WW γ gauge couplings are derived at 95% CL: −0.46 Δκ γ λ γ
