Search for the neutral Higgs bosons of the minimal supersymmetric standard model from Z\u3csup\u3e0\u3c/sup\u3e decays

Abstract

\u3cp\u3eWe present the results from a search for the light neutral scalar Higgs boson h° and the pseudoscalar Higgs boson A° of the minimal super-symmetric standard model. The analysis is based on a data sample corresponding to 71 000 hadronic Z° decays recorded with the L3 detector at LEP. No evidence for the existence of the neutral Higgs bosons h° and A° has been found. The region of h° and A° masses up to 41.5 GeV is excluded at 95% confidence level.\u3c/p\u3
