Search for the Standard Model Higgs Boson at LEP /DELPHI Collaboration ; ALEPH Collaboration ; L3 Collaboration ; OPAL Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected 2461 pb−1 of e+e− collision data at centre-of-mass energies between 189 and 209 GeV, of which 536 pb−1 have energies above 206 GeV. The data have been used to search for the Standard Model Higgs boson. [...]

Search for Neutral MSSM Higgs Bosons at LEP ; rev. version
/ALEPH Collaboration ; DELPHI Collaboration ; L3 Collaboration ; OPAL Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted within the framework of 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 for a possible Higgs boson signal.
