Two-Higgs-doublet models and the Yukawa process at LEP1

We investigate the production of Higgs bosons $A/h$ via the Yukawa process $Z\ra f\bar{f} \ra f\bar{f} A/h $ taking into account QCD corrections and fermion mass effects. We estimate the discovery reach of this process and/or bounds on the parameter space of two-Higgs doublet models which can be derived from the analysis of $b {\bar b} τ^+ τ^-$ events at LEP1. These limits have important consequences for extended models of electroweak interactions and their experimental verification/improvement are welcome.

Three-Body Decays of the Susy Higgs Bosons

In this talk I discuss three-body decays of the SUSY Higgs bosons which proceed via intermediate two-body states in which one of the particles is off-mass-shell. Some of these decays will be shown to have substantial branching ratios in some range of the SUSY parameter space.

TESTING THE $WWγ$ COUPLING AT $e^+e^-$ COLLIDERS

The production of single photons plus missing energy at future $e^{+}e^{-}$ colliders can provide a testing ground for non-standard $WWγ$ couplings. We show that even with conservative estimates of systematic errors there is still considerable sensitivity to anomalous couplings.

Higgs search in e+e- and gamma-gamma colliders

The prospects for discovering Higgs particles and studying their fundamental properties at future high--energy electron--positron and photon-photon colliders are reviewed. Both the Standard Model Higgs boson and the Higgs particles of its minimal supersymmetric extension are discussed. We also comment on a two Higgs doublet model searches at LEP 1. We update various results by taking into account the value of the top quark mass obtained by the CDF Collaboration and by including radiative corrections.
