Query: Search for Neutral MSSM Higgs Bosons at LEP   The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for
the neutral Higgs bosons which are predicted by the Minimal Supersymmetric
Standard Model (MSSM). The data of the four collaborations are statistically
combined and examined for their consistency with the background hypothesis and
with a possible Higgs boson signal. The combined LEP data show no significant
excess of events which would indicate the production of Higgs bosons. The
search results are used to set upper bounds on the cross-sections of various
Higgs-like event topologies. The results are interpreted within the MSSM in a
number of "benchmark" models, including CP-conserving and CP-violating
scenarios. These interpretations lead in all cases to large exclusions in the
MSSM parameter space. Absolute limits are set on the parameter tanb and, in
some scenarios, on the masses of neutral Higgs bosons.
