| 英文摘要 | We search for a Higgs particle with anomalous couplings in the e+e-> H gamma, e(+)e(-)-> HZ and e(+)e(-)-> He(+)e(-) processes with the L3 detector at LEP. We explore the mass range 70 GeV < m(H) < 170 GeV using 176 pb(-1) of integrated luminosity at a center-of-mass energy of root s = 189GeV. The Higgs decays H -> b (b) over bar, H -> gamma gamma and H -> Z gamma are considered in the analysis. No evidence for anomalous Higgs production is found. This is interpreted in terms of limits on the anomalous couplings d, d(B), Delta g(1)(Z) and Delta kappa(gamma). Limits on the Gamma(H -> gamma gamma) and Gamma(H -> Z gamma) partial widths in the explored Higgs mass range are also obtained. (C) 2000 Elsevier Science B.V. All rights reserved. |
