论文摘要
手性较高的自旋重力在重力的最小自旋扩展方面是独一无二的，并且在平坦和（抗） - de保姆空间中具有简单的局部作用。它必须在四个维度上是任何其他更高旋转理论的封闭子部门，这使其成为重要的构件和基准。使用扁平空间版本为简单起见，我们对手性理论中的量子校正进行了彻底的研究，从而增强了我们较早的结果ARXIV：1805.00048。即使相互作用是天真的，我们表明，由于较高的自旋对称性，我们表明在一个，三分和四点振幅中没有紫外线差异。我们还提出了广告手性理论应表现出相似特性的论点。结果表明，手性理论以$ u（n）$，$ so（n）$和$ usp（n）$ groups的态度承认了杨米尔斯的仪表，这让人联想到字符串理论中的陈 - 帕顿对称性。
Chiral Higher Spin Gravity is unique in being the smallest higher spin extension of gravity and in having a simple local action both in flat and (anti)-de Sitter spaces. It must be a closed subsector of any other higher spin theory in four dimensions, which makes it an important building block and benchmark. Using the flat space version for simplicity, we perform a thorough study of quantum corrections in Chiral Theory, which strengthen our earlier results arXiv:1805.00048. Even though the interactions are naively non-renormalizable, we show that there are no UV-divergences in two-, three- and four-point amplitudes at one loop thanks to the higher spin symmetry. We also give arguments that the AdS Chiral Theory should exhibit similar properties. It is shown that Chiral Theory admits Yang-Mills gaugings with $U(N)$, $SO(N)$ and $USp(N)$ groups, which is reminiscent of the Chan-Paton symmetry in string theory.
