CP-Violating MSSM Higgs Bosons in the Light of LEP 2
نویسنده
چکیده
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-violating MSSM Higgs bosons. We show that the bounds established by LEP 2 on the MSSM Higgs sector may be substantially relaxed at low and intermediate values of tanβ in the presence of CP violation, and comment on possible Higgs boson signatures at LEP 2 within this framework.

Search for CP Violating neutral Higgs bosons in the MSSM at LEP
The LEP collaborations ALEPH, DELPHI, L3 and OPAL have searched for the neutral Higgs bosons which are predicted within the framework of the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and show no signicant excess of events which would indicate the production of Higgs bosons. The search results are thus used to set upper bounds on...
متن کاملSearches 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...

متن کاملLEP Limits on CP - Violating Non - Minimal Higgs Sectors
We derive a sum rule which shows how to extend LEP limits on the masses of the lightest CP-even and CP-odd Higgs bosons of a CP-conserving two-Higgs-doublet model to any two Higgs bosons of a general CP-violating two-Higgs-doublet model. We generalize the analysis to a Higgs sector consisting of an arbitrary number of Higgs doublets and singlets, giving explicit limits for the CP-conserving and...
متن کاملCP-violating Higgs at Tevatron
We analyze the prospect for observing the intermediate neutral Higgs (h2) boson in its decay to two lighter Higgs bosons (h1) at the Tevatron in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+ 4-jets+ E/T channel from pp̄ → W h2 → W h1h1 → lνlbb̄bb̄, with two or three tagged b jets. We found that it is very hard to observe this signature in the LEP-...
