Can minimal supersymmetry be ruled out at CERN LEP 200 frome+e−→ZφHiggs-boson searches?

We show that if the CERN collider LEP 200 is capable of excluding a standard-model Higgs boson with $m_{\phi }=m_Z$ via the process $e^{+}{e}^{-}\to Z\phi \to {\ell }^{+}{\ell }^{-}q\overline{q}$, then the minimal supersymmetric model would also be excluded by similar searches for the light and heavy neutral Higgs scalars of minimal supersymmetry. We discuss how this might be achieved using the production rate and final-state particle distributions. An integrated luminosity of about 4 ${\mathrm{fb}}^{-1\mathrm{}}$ should be sufficient to exclude at the $4\sigma$ level a standard-model Higgs boson with $m_{\phi }=m_Z$; with $b$ tagging, 0.7 ${\mathrm{fb}}^{-1\mathrm{}}$ may suffice. If a positive Higgs-boson signal is seen, minimal supersymmetry might not be distinguishable from the standard model in the $Z\phi$ mode alone.
