2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/37009The four LEP experiments Aleph, Delphi, L3 and Opal updated their searches for pair production of charged Higgs bosons using more than 210/pb luminosity collected per experiment in the year 2000. Combining it with previously collected data, a significant deviation from background (equivalent to 4.4 sigma) is found by the L3 collaboration for low values of the branching ratio H+/- -> tau nu around masses of about 68 GeV. This excess is however not seen by the other LEP collaborations and thus a lower limit on the charged Higgs mass is set at 78.5 GeV at 95% confidence level. All results reported here are still preliminary.4 pages, 4 figures, LaTex, to be published in the Proceedings of XXXVIth Rencontre de Moriond, Electroweak Interactions and Unified Theories, March 2001High Energy Physics - Experimenttext
