摘要:

我们考虑具有软超对称破缺项的超对称QCD作为电弱对称破缺的动力学。我们发现各种优势相比,非超对称模型,如自然纳入的动态顶夸克质量产生(顶色机制),玻色子对凝聚(复合希格斯场)的存在和一个大的异常尺寸的复合算子治愈的变味中性流和S参数的technicolor理论的危机。弱耦合描述(Seiberg对偶)的知识使我们能够在强耦合理论中进行微扰计算。在大味理论中,微扰计算在对偶描述中是可靠的,人们可以找到一个具有手征对称性破缺的稳定真空。顶/底夸克和希格斯玻色子通过动力学产生的超势获得质量。

英文摘要:

We consider a supersymmetric QCD with soft supersymmetry breaking terms as the dynamics for the electroweak symmetry breaking. We find various advantages compared to the non-supersymmetric models, such as a natural incorporation of the dynamical top-quark mass generation (the topcolor mechanism), the existence of a boson-pair condensation (the composite Higgs fields) and a large anomalous dimension of the composite operator to cure the flavor-changing-neutral-current and the S-parameter crises of the technicolor theories. The knowledge of the weakly coupled description (the Seiberg duality) enables us to perform perturbative computations in strongly coupled theories. Working in a large flavor theory where perturbative calculations are reliable in the dual description, one can find a stable vacuum with chiral symmetry breaking. The top/bottom quarks and also the Higgsinos obtain masses through a dynamically generated superpotential.
