For a top quark mass fixed to its measured value, we find natural regions of minimal supergravity parameter space where all squarks, sleptons, and heavy Higgs scalars have masses far above 1 TeV and are possibly beyond the reach of the Large Hadron Collider at CERN. This result is simply understood in terms of "focus point" renormalization group behavior and holds in any supergravity theory with a universal scalar mass that is large relative to other supersymmetry breaking parameters. We highlight the importance of the choice of fundamental parameters for this conclusion and for naturalness discussions in general.
对于固定为其测量值的顶夸克质量,我们发现了最小超引力参数空间的自然区域,其中所有的 squarks、sleptons 和重希格斯标量的质量都远高于 1 TeV,并且可能超出了欧洲核子研究中心大型强子对撞机的探测范围。这个结果可以简单地用“聚焦点”重整化群行为来理解,并且在任何具有相对于其他超对称破缺参数较大的通用标量质量的超引力理论中都成立。我们强调了基本参数选择对于这个结论以及一般自然性讨论的重要性。
