Higgs boson searches at LEP

In this paper we report on the legacy of Higgs boson searches at LEP. Specifically, the results of the statistical combination of the searches carried out by the ALEPH, DELPHI, L3 and OPAL experiments are presented. In the search for the Standard Model (SM) Higgs boson, a signal with m_h < 114.4 GeV/c² has been excluded at the 95% confidence level (CL) or higher. The LEP collaborations also carried out extensive searches for Higgs particles predicted by many scenarios beyond the Standard Model. Here we can only report on a very small fraction of these searches and refer the reader to the complete list of LEP-combined search results.
