A search was performed for the associated production of two different Higgs bosons via a virtual Z0 in e+e- annihilation (e+e- → h1 0h2 0) using the JADE detector at PETRA. This was motivated by the interpretation of the monojet events observed at the CERN pp collider as anomalous Z0 decays into two neutral Higgs bosons (h1 0 and h2 0), where h1 0 is stable and escapes detection while h2 0 decays into hadrons. Single- or di-jet events with large momentum imbalance are then expected at PETRA energies. No evidence for such events was found in our data; this excludes h2 0 masses in the range of 1 to 21 GeV with 95% CL, if the branching fraction for Z0 → h1 0h2 0 is a larger than one half that for Z0 → vμvμ. The possibility that the monojets could originate from supersymmetric higgsino production from Z0 decay is also examined.
