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 gamma gauge couplings are derived at 95% CL: - 0.46 < Delta kappa(gamma) < 0.57 and - 0.86 < lambda(gamma) < 0.75. (C) 1998 Elsevier Science B.V.
