Search for neutral Higgs bosons of the minimal supersymmetric standard model in e+e−interactions at s = 130 - 183 GeV

Abstract A search for the lightest neutral scalar and neutral pseudoscalar Higgs bosons in the Minimal Supersymmetric Standard Model is performed on data collected at LEP by the L3 detector at center-of-mass energies 130 GeV ≤ s ≤183 GeV . No significant excess of events is observed. Limits on the masses of the lightest neutral and pseudoscalar Higgs bosons are given as a function of tan β . Lower mass limits at the 95% confidence level are set at m h >70.7 GeV and m A >71.0 GeV .
