我们用局部尺度对称性构建了四个维度的最大超引力，作为原始 Cremmer-Julia 理论的变形。包括标准测量的不同理论通过携带 56+912 个参数的嵌入张量进行参数化。我们确定可能的规范组的形式并计算出完整的场方程组。结果，我们获得了在四个维度上与 N = 8 超对称性兼容的最一般的耦合。这些理论的一个特点是没有作用，并且对有效宇宙学常数有额外的积极贡献。此外，这些测量通常是双子测量，即同时涉及电场和磁场矢量场。
We construct maximal supergravity in four dimensions with local scaling symmetry as deformation of the original Cremmer-Julia theory. The different theories which include the standard gaugings are parametrized by an embedding tensor carrying 56 + 912 parameters. We determine the form of the possible gauge groups and work out the complete set of field equations. As a result we obtain the most general couplings compatible with N = 8 supersymmetry in four dimensions. A particular feature of these theories is the absence of an action and an additional positive contribution to the effective cosmological constant. Moreover, these gaugings are generically dyonic, i.e. involve simultaneously electric and magnetic vector fields.
