Abstract
If the standard electroweak gauge model is extended to include two or more Higgs doublets, there may be a neutral Higgs boson h which is lig ht (with a mass of say 10 GeV) but the hZZ coupling is suppressed so t hat it has so far escaped experimental detection. However, the effecti ve hhZZ coupling is generally unsuppressed; hence, the decay of Z into two light Higgs bosons plus a fermion-antifermion pair may have an ob servable branching fraction, especially if h decays invisibly as, for example, in the recently proposed doublet Majoron model.
