The Status of the Minimal Supersymmetric Standard Model and Beyond
The minimal supersymmetric extension of the Standard Model (MSSM) is reviewed. In the most general framework with minimal field content and R-parity conservation, the MSSM is a 124-parameter model (henceforth called MSSM-124). An acceptable phenomenology occurs only at exceptional points (and small perturbations around these points) of MSSM-124 parameter space. Among the topics addressed in thi...
متن کاملBeyond the Minimal Supersymmetric Standard Model
Several topics from the subject of supersymmetric field theories are reviewed. We first present the structure of the minimal supersymmetric standard model. Next we discuss the issue of the doublet-triplet splitting problem in supersymmetric grand unified theories. We show some necessary conditions which a viable model has to satisfy and present three models which successfully solve the doublet-...

متن کاملThe Minimal Supersymmetric Standard Model
We present a detailed and complete calculation of the loop corrections to the mass difference ∆m B 0 d /m B 0 d. We include charginos and scalar up quarks as well as gluinos and scalar down quarks on the relevant loop diagrams. We include the mixings of the charginos and of the scalar partners of the left and right handed quarks. We find that the gluino contribution to this quantity is importan...
متن کاملMinimal Supersymmetric Standard Model
In the minimal supersymmetric standard model, the Higgs sector has two unknown parameters, usually taken to be tanβ ≡ v2/v1 and mA, the mass of its one physical pseudoscalar particle. By minimizing the minimum of the Higgs potential along a certain direction in parameter space, it is shown that mA = MZ + radiative correction, and if one further plausible assumption is made, tanβ > √ 3. If there...
