具有规范R对称性和闵可夫斯基真空的超引力允许自发的超对称破缺，因此，为建立现象学相关的超引力模型提供了一个框架。在这封信中，我们开始研究这些超引力的双拷贝结构。我们认为，在一般情况下，我们希望他们的散射振幅描述的类型（自发破缺规范理论）的双副本（规范理论与破缺超对称性）。我们给出了一个简单的实现，其中所产生的超引力具有U（1）R规范对称性、自发破缺的N=2超对称性和大质量引力子.这是规范超引力和自发破缺超对称性理论的第一个双拷贝构造实例。这个结构以一种直接的方式扩展到一个有或没有自发规范对称破缺的规范杨-米尔斯-爱因斯坦超引力理论的大家族。
Supergravities with gauged R symmetry and Minkowski vacua allow for spontaneous supersymmetry breaking and, as such, provide a framework for building supergravity models of phenomenological relevance. In this Letter, we initiate the study of double copy constructions for these supergravities. We argue that, on general grounds, we expect their scattering amplitudes to be described by a double copy of the type (spontaneously broken gauge theory)⊗ (gauge theory with broken supersymmetry). We present a simple realization in which the resulting supergravity has U(1)_{R} gauge symmetry, spontaneously broken N=2 supersymmetry, and massive gravitini. This is the first instance of a double copy construction of a gauged supergravity and of a theory with spontaneously broken supersymmetry. The construction extends in a straightforward manner to a large family of gauged Yang-Mills-Einstein supergravity theories with or without spontaneous gauge-symmetry breaking.
