Singlet Extensions of the MSSM
The Higgs sector of the MSSM may be extended to solve the μ problem by the addition of a gauge singlet scalar field. We consider the consequences of the singlet on the Higgs and neutralino states compositions. We discuss the potential for discovering Higgs bosons of singlet models and observing the unique multilepton signatures of the extended neutralino sector.

متن کاملProperties of the Lightest Neutralino in MSSM Extensions
We study neutralino sectors in extensions of the MSSM that dynamically generate the μ-term. The extra neutralino states are superpartners of the Higgs singlets and/or additional gauge bosons. The extended models may have distinct lightest neutralino properties which can have important influences on their phenomenology. We consider constraints on the lightest neutralino from LEP, Tevatron, and (...
متن کاملCDF Multi-Muon Events and Singlet Extensions of the MSSM
We discuss a generalization of the minimal supersymmetric extension of the Standard Model in the form of three additional singlet superfields, which would explain the essential features of the CDF multi-muon events presented recently: a large production cross section of ∼ 100 pb originates from the production of a CP-odd scalar A with a mass in the 70 – 80 GeV range and a large value of tanβ ∼ ...
