Scientific paper

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 $H\to
\gamma\gamma$ is above the one into fermion pairs, which is evaluated also at
the 1-loop level.
