Another Look at Charged Higgs Boson Production at LEP
  The current atmospheric and solar neutrino experimental data favors the bi-maximal mixing solution of the Zee-type neutrino mass matrix in which neutrino masses are generated radiatively. This model requires the existence of a weak singlet charged Higgs boson. While low energy data are unlikely to further constrain the parameters of this model, the direct search of charged Higgs production at the CERN LEP experiments can provide useful information on this mechanism of neutrino mass generation by analyzing their data with electrons and/or muons (in contrast to taus or charms) in the final state with missing transverse energies. We also discuss the difference in the production rates of a weak singlet from a weak doublet charged Higgs boson pairs at LEP.
