论文摘要
在这里,我们从Vasiliev的双重版本的一阶动作开始,用于无质量自旋2颗粒(线性化的一阶爱因斯坦 - 希尔伯特),并通过kaluza-klein尺寸从$ d+1 $ $ d $ d $ d $ dimensions(一组双重质量spin-2型号)降低。该集合包括巨大的“ BR”模型,这是Spin-1 Cremmer-Scherk模型的自旋2类似物。在我们的方法中,线性化的Riemann曲率来自功能约束的解决方案。在$ d = 2+1 $中,BR模型可以写为新的Bimetric型号的线性化版本,用于大型Gravitons。在线性化的差异性下,我们还具有新的大型Spin-2模型,在任意维度上不变。它是根据非对称秩-2张量和混合对称张量给出的。
Here we start from a dual version of Vasiliev's first order action for massless spin-2 particles (linearized first order Einstein-Hilbert) and derive, via Kaluza-Klein dimensional reduction from $D+1$ to $D$ dimensions, a set of dual massive spin-2 models. This set includes the massive "BR" model, a spin-2 analogue of the spin-1 Cremmer-Scherk model. In our approach the linearized Riemann curvature emerges from a solution of a functional constraint. In $D=2+1$ the BR model can be written as a linearized version of a new bimetric model for massive gravitons. We also have a new massive spin-2 model, in arbitrary dimensions, invariant under linearized diffeomorphisms. It is given in terms of a non symmetric rank-2 tensor and a mixed symmetry tensor.
