dc.description.abstract	Nonminimal neutral Higgs bosons decaying into a muon pair were searched for using the Mark II detector at the SLAC e+e- collider PEP at SQRT(s) =29 GeV. A neutral scalar Higgs boson H0s can be produced accompanied by a pseudoscalar neutral Higgs boson H0p via a virtual Z0. If the mass of one of the Higgs bosons is between the muon pair threshold and the kaon pair threshold, it may decay predominantly into a muon pair. We looked for muon pair+jet(s) [e+e-->HsHp->(mu+mu-)+q qbar(tau+tau-)] and three-muon-pair [e+e>HsHp->3(Hp)->3(mu+mu-)] topologies. We found no evidence for these signals above the known background level, and we obtained limits on Gamma(Z0->HsHp) as a function of the Higgs-boson masses.
