Search for nonminimal neutral Higgs bosons fromZ-boson decays

Abstract
Using the Mark II detector at the SLAC Linear Collider, we search for decays of the Z boson to a pair of nonminimal Higgs bosons (ZHs0 Hp0), where one of them is relatively light (≲10 GeV). We find no evidence for these decays and we obtain limits on the ZHs0 Hp0 coupling as a function of the Higgs-boson masses.
