我们提出了一个简单的四维模型，其中异常介导的超对称性破缺自然占主导地位。核心要素是，隐藏的部门是一个强耦合的红外固定点附近的几十年的能量低于普朗克尺度。强重整化效应将隐藏扇区与可见扇区隔离。超对称性是动态破缺的，不需要小的输入参数。该模型提供了一个自然的和经济的解释之间的层次结构的超对称性破坏的规模和普朗克尺度，同时允许异常调解，以解决弱尺度超对称性所带来的现象学挑战。特别是，改变味道的中性电流自然接近其实验极限。
We present a simple four-dimensional model in which anomaly mediated supersymmetry breaking naturally dominates. The central ingredient is that the hidden sector is near a strongly-coupled infrared fixed-point for several decades of energy below the Planck scale. Strong renormalization effects then sequester the hidden sector from the visible sector. Supersymmetry is broken dynamically and requires no small input parameters. The model provides a natural and economical explanation of the hierarchy between the supersymmetry-breaking scale and the Planck scale, while allowing anomaly mediation to address the phenomenological challenges posed by weak scale supersymmetry. In particular, flavor-changing neutral currents are naturally near their experimental limits.
