Status of 2HDM with a Light Higgs Particle

Abstract

Present data do not rule out the light neutral Higgs particle h or A with mass below 40--50 GeV in the framework of the general 2HDM ("Model II"). The status of this model in a light of existing LEP I data and a potential of the new muon experiment (g-2), the measurement of photon-gluon and gluon-gluon fusion at HERA as well as photon-photon fusion at low energy gamma gamma NLC is discussed.
