Abstract

A search for the lightest neutral CP-even and the neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 233.2 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies 192-202 GeV. No signal is observed and lower mass limits are given as a function of tan β for two scalar top mixing hypotheses. For tan β greater than 0.8, they are mh > 83.4 GeV and mA > 83.8 GeV at 95% confidence level.
