| Abstract |
Anomalous couplings of the Higgs boson are searched for through the processes e+e- ? H?, e+e- ? e+e-H and e+e- ?HZ. The mass range 70 GeV<mH < 190 GeV is explored using 602 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies vs = 189-209 GeV. The Higgs decay channels H?f¯f, H???, H?Z? 92 L3 Collaboration / Physics Letters B 589 (2004) 89-102 and H?WW(*) are considered and no evidence is found for anomalous Higgs production or decay. Limits on the anomalous couplings d, dB, gZ 1 , ?? and ? 2 are derived as well as limits on the H??? and H?Z? decay rates.
