TL;DR
This paper reports on combined searches for various non-Standard Model Higgs bosons conducted by LEP experiments, exploring multiple decay modes and extensions of the Standard Model.
Contribution
It presents comprehensive flavor-independent and specialized searches for non-SM Higgs bosons, including fermiophobic, invisibly decaying, charged, and MSSM neutral Higgses, across four LEP experiments.
Findings
No significant evidence for non-SM Higgses found.
Constraints set on Higgs boson masses and couplings.
Results improve limits on various non-SM Higgs scenarios.
Abstract
The four LEP experiments, ALEPH, DELPHI, L3 and OPAL, have searched for Higgs bosons predicted by a large number of extensions of the Standard Model. Flavor independent searches are presented for the hZ process in which the h decays hadronically. Search results are also presented for fermiophobic Higgs bosons, invisibly decaying Higgs bosons, charged Higgs bosons and the neutral Higgs bosons in the MSSM.
