摘要：

A search for the lightest neutral CP-even and neutral CP-odd Higgs bosons of the minimal supersymmetric standard model is performed using 216.6 pb(-1) of data collected with the L3 detector at LEP at centre-of-mass energies between 203 and 209 GeV. No indication of a signal is found. Including our results from lower centre-of-mass energies, lower limits on the Higgs boson masses are set as a function of tan beta for several scenarios. For tan beta greater than 0.7 they are m(h) > 84.5 GeV and m(A) > 86.3 GeV at 95% confidence level. (C) 2002 Published by Elsevier Science B.V.
