我们介绍了一个N=1超引力模型，它有一个非常简单的隐扇区，它与最小超对称标准模型的电弱规范扇区和希格斯扇区相耦合。在经典能级，超对称性和SU(2)×U(1)都自发破缺，真空能量消失。两个实平面方向控制着两个对称破缺标度m(3/2)和m(Z)。这两个无质量标量是规范单态和标准希格斯玻色子。所有其他未观测到的粒子都有m(3/2)量级的质量。这可能是研究自然度与观测到的质量等级相容的一个新的起点。
We introduce a N=1 supergravity model with a very simple hidden sector coupled to the electroweak gauge and Higgs sectors of the minimal supersymmetric standard model. At the classical level, supersymmetry and SU(2)×U(1) are both spontaneously broken, with vanishing vacuum energy. Two real flat directions control the two symmetry-breaking scales m(3/2) and m(Z). The two massless scalars are a gauge singlet and the standard Higgs boson. All other unobserved particles have masses of order m(3/2). This may be a new starting point for studying the compatibility of naturalness with the observed mass hierarchies.
