The Status of MSSM Higgs Boson Searches at LEP

نویسنده

  • Andy Hocker
چکیده

The most recently available results from searches conducted by the four LEP experiments at 189 GeV center-of-mass energy for Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) are presented. No evidence for a signal has been observed, and the null result is used by the experiments, both individually and collectively, to exclude regions of the MSSM parameter space and to set lower limits on Higgs boson masses at 95% con dence level in constrained MSSM scenarios.

MSSM Constraints from Higgs Boson Searches

The LEP era has brought immense progress in searches for Higgs bosons over the last 12 years which will guide searches at future colliders. The evolution of the Higgs boson mass limits is reviewed with the focus on results from general parameter scans in the Minimal Supersymmetric extension of the Standard Model (MSSM) in contrast to the so-called benchmark limits. The hint for a Standard Model...

CP-Violating MSSM Higgs Bosons in the Light of LEP 2

In the MSSM, the CP parities of the neutral Higgs bosons may be mixed by radiative effects induced by explicit CP violation in the third generation of squarks. To allow for this possibility, we argue that the charged Higgs-boson mass and tan β should be used to parametrize the MSSM Higgs sector. We introduce a new benchmark scenario of maximal CP violation appropriate for direct searches of CP-...

Searches for Neutral Higgs Boson and Interpretations in the MSSM at LEP

This paper discusses recent publications of the LEP collaborations DELPHI, L3 and OPAL on searches for Higgs bosons motivated by MSSM scenarios as well as their interpretation in the MSSM. With the final publication of the LEP collaborations available or awaited, more and more interpretations in different MSSM models, including both CP conserving and CP violating, become available. Also special...

Search for a neutral Higgs boson in MSSM

The four LEP collaborations have searched for neutral Higgs bosons predicted within the MSSM. The experimental results included the searches for neutral Higgs bosons at LEP1 and LEP2 in final states as expected in the MSSM. The combined LEP data show no significant excess of events over the expectation from the Standard Model predictions. The search results are interpreted within the MSSM for a...
