摘要

We investigate the possibility of a multi-Higgs doublet model where the lightest neutral Higgs boson ( $h^0$ ) decouples from the fermion sector. We are partially motivated by the four $\ell^+\ell^-\gamma\gamma$ events with $M_{\gamma\gamma}\simeq60$ \,GeV recently observed by the L3 collaboration, which could be a signal for $Z\to (Z^*\to \ell^+\ell^-)+(h^0\to \gamma\gamma)$ . Collider signatures for the additional physical Higgs bosons present in such models are discussed.
