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