|Review of Higgs boson searches at LEP|
The LEP collider allowed to search for Higgs bosons with various production and decay modes. Beside standard and supersymmetric Higgs bosons, LEP proved to be sensitive to more exotic particles, such as those with much lower production rates or with non-standard decays, like decays into invisible products, gauge bosons or into other Higgs bosons. Complementary constraints on Higgs boson masses were also derived from precise measurements of electroweak observables. In this article, LEP results as of summer 2003 are reviewed.
