Abstract
We study the dominant decays of the lightest Higgs boson in models with 2 and 3 Higgs doublets, for the case when its couplings to fermions are absent at tree-level. It is found that the branching ratio for the decay is above the one into fermion pairs, which is evaluated also at the 1-loop level.
