我们研究了可以避免光超伴的论点，作为超对称辐射电弱对称性破缺的暗示。我们认为，从弦理论和产生μ项的标准方法的观点来看，参数之间的消去并不是一个普遍的特征。在软超对称破缺拉格朗日量中，mz与参数的相关系数可以变小，但在电弱尺度下，这些相同的机制导致了更轻的超伴质量。因此，我们加强了胶子、中性子和电荷子是轻的并且可能在费米实验室的Tevatron和线性对撞机中产生的暗示。
We examine arguments that could avoid light superpartners as an implication of supersymmetric radiative electroweak symmetry breaking. We argue that, from the point of view of string theory and standard approaches to generating the μ term, cancellations among parameters are not a generic feature. While the coefficients relating MZto parameters in the soft supersymmetry breaking Lagrangian can be made smaller, these same mechanisms lead to lighter superpartner masses at the electroweak scale. Consequently we strengthen the implication that gluinos, neutralinos, and charginos are light and likely to be produced at the Fermilab Tevatron and a linear collider.
