The MSSM in the Light of Precision Data

چکیده
The potential of present and anticipated future electroweak precision data, including the Higgs boson and top quark masses, for testing quantum effects of the electroweak theory is investigated in the context of the Minimal Supersymmetric Standard Model (MSSM). The present status of the theoretical predictions is analyzed. The impact of the parametric uncertainties from the experimental errors of the input parameters is studied, and an estimate for the remaining uncertainties from unknown higher-order corrections is given both in the Standard Model (SM) and the MSSM. Examples of electroweak precision tests in the mSUGRA scenario and the unconstrained MSSM are analyzed, and the status of the global fit to all data is discussed. to appear in the proceedings of the workshop “Electroweak precision data and the Higgs mass”, DESY Zeuthen, February 2003 email: [email protected] email: [email protected] The MSSM in the Light of Precision Data S.

The Minimal supersymmetric extension of the Standard Model (MSSM) with light stops, charginos or pseu-doscalar Higgs bosons has been suggested as an explanation of the too high value of the branching ratio of the Z 0 boson into b quarks (R b anomaly). A program including all radiative corrections to the MSSM at the same level as the radiative corrections to the SM has been developed and used to...
متن کاملElectroweak Precision Observables in the Minimal Supersymmetric Standard Model
The current status of electroweak precision observables in the Minimal Supersymmetric Standard Model (MSSM) is reviewed. We focus in particular on the W boson mass, M W , the effective leptonic weak mixing angle, sin 2 θ eff , the anomalous magnetic moment of the muon, (g − 2) µ , and the lightest CP-even MSSM Higgs boson mass, m h. We summarize the current experimental situation and the status...

When realizing the Minimal Supersymmetric Standard Model (MSSM) within a (simple) Grand Unified Theory (GUT), the predicted ranges for the strong coupling and the ratio of two Higgs doublet expectation values are strongly correlated with the weak angle and the t-quark mass. (The latter are extracted from precision data.) We spell out those relations and point out the implication for the mass of...
متن کاملMuon g − 2 and precision electroweak physics in the MSSM
The minimal supersymmetric extension of standard model (MSSM) is examined by analyzing its quantum effects on the precision electroweak measurements and the muon g − 2. We examine carefully the effects of light charginos and neutralinos that are found to improve the fit to the electroweak data. We identify two distinct regions on the (μ,M2)-plane that fit well to the electroweak data and give s...
