Abstract
We investigate the three-particle decays of heavy Higgs bosons in the Weinberg-Salam model with two Higgs doublets. The dominant decay mode is\(H \to VH' \to f\bar fH'\), if the mixing angles in the Higgs sector are not very extreme. The decay width is a few percent of the decayH→VH′, atm H =100−150 GeV it is about a few MeV. The fermion energy distribution can discriminate from the case of one Higgs doublet.
