Query: Search for the Standard Model Higgs boson at LEP   The combined results of the search for the Standard Model Higgs boson from
the four LEP experiments are given. These results are based on the full data
sample collected by ALEPH, DELPHI, L3 and OPAL at centre-of-mass energies up to
209GeV, corresponding to a total integrated luminosity of about 2.5fb-1. A
slight excess of events over the background expectation is found at the 2sigma
level, originating mainly from the ALEPH 4-jet channel. This excess is
compatible with what expected for the production of a SM Higgs boson with a
mass of 115.6GeV/c2. A combined 95% confidence level lower limit of 114.1GeV/c2
on the mass of the Standard Model Higgs boson is derived.
