Search for anomalously coupling and fermiophobic Higgs Bosons

Searches for fermiophobic Higgs boson decaying into photon or weak boson pairs have been performed at LEP with the data collected at center of mass energies up to 209 GeV. A summary of several analyses allowing to cover some hundred different final state topologies is presented. No statistically significant evidence of fermiophobic Higgs boson has been found. A lower limit on the Higgs boson mass is presented. More generally, anomalous couplings of the Higgs boson are searched for through the processes e +e − → H 0 γ, e +e − → e +e −H 0 and e +e − → H 0Z by the L3 collaboration. The Higgs decay channels H 0 → ff, H 0 → γγ, H 0 → Zγ and H 0 → WW(∗) are considered and no evidence is found for anomalous Higgs production or decay and limits are put.
