标题： A unique coupling of the massive spin-2 field to supergravity

摘要： 我们证明，在四维中，质量自旋-2场与未变形的N=1超引力的耦合是唯一的，导致与黎曼张量的特定非最小耦合。 质量自旋-2耦合再现了开弦理论中振子模式的耦合，而质量自旋-1耦合包含一个高阶导数项，该术语在引力冲击波背景中预期会破坏因果性。 我们认为，在Regge极限中解决因果性和单位性界限需要引入无限多个高自旋场，类似于弦理论中的Regge轨迹，因此提供了支持四维中具有最小超对称性的弦灯柱原理的论据。 为了得到这个结果，我们构建了具有N=1超对称性的质量自旋-2多重态的一般应力-能量张量多重态。 显示英文摘要

摘要： We show that the coupling of a massive spin-2 field to undeformed N=1 supergravity in four dimensions is unique, leading to a specific non-minimal coupling to the Riemann tensor. The massive spin-2 coupling reproduces the one of an oscillator mode in open string theory, while the massive spin-1 coupling includes a higher-derivative term that is expected to violate causality in the background of a gravitational shock wave. We argue that the resolution of causality and the unitarity bound in the Regge limit require the introduction of infinitely many higher-spin fields similar to the Regge trajectories in string theory, therefore providing an argument in favour of the string lamppost principle with minimal supersymmetry in four dimensions. To obtain this result, we construct the general stress-energy tensor multiplet for the massive spin-2 multiplet with N=1 supersymmetry.
