چکیده
The connection between the scales of SU(2) × U(1) gauge symmetry breaking and supersymmetry breaking is didactically displayed in the framework of a T.O.Y. (Theory Overestimating Yukawas) model, a version of the (M + 1)SSM (supersymmetric extension of the standard model with a gauge singlet) in which the relevant parameters are determined in the fixed point regime. Some conspicuous features of supersymmetric particle physics are reviewed in the light of this simplified model. An alternative theory corresponding to lim (M + 1)SSM −→ M SSM, leads to interesting inequalities among the supersymmetric breaking parameters of the M SSM.

Electroweak Symmetry Breaking in Supersymmetric Gauge-Higgs Unification Models
We examine the Higgs mass parameters and electroweak symmetry breaking in supersymmetric orbifold field theories in which the 4-dimensional Higgs fields originate from higher-dimensional gauge supermultiplets. It is noted that such gauge-Higgs unification leads to a specific boundary condition on the Higgs mass parameters at the compactification scale, which is independent of the details of sup...
متن کاملElectroweak Symmetry Breaking due to Confinement
Within the framework of gauge mediated supersymmetry breaking, we consider an electroweak symmetry breaking pattern in which there is no conventional µ term. The pattern is made appealing through realizing it as a low energy effective description of a supersymmetric Yang-Mills theory which is of confinement. Phenomenological implications are discussed.
متن کاملSolving the μ Problem in Gauge Mediated Supersymmetry Breaking Models with Flavor Symmetry
We suggest a solution to the μ problem of gauge mediated supersymmtery breaking models based on flavor symmetries. In this scenario the μ term arises through the vacuum expectation value of a singlet scalar field which is suppressed by a flavor symmetry factor relative to the scale of dynamical SUSY breaking. The same flavor symmetry also ensures that the soft SUSY breaking parameter Bμ is not ...
متن کاملA Supersymmetric Model with the Gauge Symmetry
A supersymmetric model with two copies of the Standard Model gauge groups is constructed in the gauge mediated supersymmetry breaking scenario. The supersymmetry breaking messengers are in a very simple form. The Standard Model is obtained after first step gauge symmetry breaking. In the case of one copy of the gauge interactions being strong, a scenario of electroweak symmetry breaking is disc...
متن کاملMinimally Fine-Tuned Supersymmetric Standard Models with Intermediate-Scale Supersymmetry Breaking
We construct realistic supersymmetric theories in which the correct scale for electroweak symmetry breaking is obtained without significant fine-tuning. We consider two classes of models. In one class supersymmetry breaking is transmitted to the supersymmetric standard model sector through Dirac gaugino mass terms generated by a D-term vacuum expectation value of a U(1) gauge field. In the othe...
متن کاملSupersymmetry Breaking and Gauge Mediation
We review recent works on supersymmetry breaking and gauge mediation. We survey our current understanding of dynamical supersymmetry breaking mechanisms and describe new model building tools using duality, meta-stability, and stringy construction. We discuss phenomenological constraints and their solutions, paying attentions to issues with gaugino masses and electroweak symmetry breaking.
