论文摘要
表明Kerr-Schild双复制自然地扩展到所有自由对称仪表字段，并在任何维度上传播$（a）ds $。与标准的低自旋案例类似，高旋转的多拷贝与零，单副本和双拷贝同在。由量规对称固定的Fronsdal Spin $ S $场方程的质量术语和零副本的质量似乎都非常微调，以适应由高旋转对称性组织的多拷贝模式。在黑洞一侧，这个奇怪的观察填充了克尔解决方案的神奇特性列表。
Kerr-Schild double copy is shown to extend naturally to all free symmetric gauge fields propagating on $(A)dS$ in any dimension. Similarly to the standard lower-spin case, the higher-spin multicopy comes along with the zeroth, single, and double copies. The mass-like term of the Fronsdal spin $s$ field equations fixed by gauge symmetry and the mass of the zeroth copy both appear to be remarkably fine-tuned to fit the multicopy pattern forming a spectrum organized by higher-spin symmetry. On the black hole side this curious observation fills up the list of miraculous properties of the Kerr solution.
