Abstract

Multi-Higgs-boson production in $Z^{0}$ decays is discussed in the context of low-energy supergravity models. For Higgs-boson masses lighter than about 20 GeV, $Z^{0} \to H_{2}^{0} H_{2}^{0} H_{3}^{0}$ naturally has a branching ratio in the range $10^{- 4}$ - $10^{- 6}$ . $Z^{0} \to H_{2}^{0} H_{2}^{0} l \bar{l}$ , where $l$ is a neutral or charged lepton, has a branching ratio in the same range if $m_{H_{2}} < 10$ GeV. Detection of these processes will give information about the structure of the Higgs sector and about the $HHZZ$ and $HHH$ couplings.
