论文摘要

我们首次在涉及标量,磁通岩和重力的抗De Sitter空间(AD)中首次提出经典的多粒解决方案。它们是通过多粒子电流递归定义的,这些电流将其降低到平面限制中的贝伦德 - 吉利电流。该结构使用删除非物理边界贡献的一般处方对树级边界相关器进行了紧凑的定义。与平坦的空间扰动类似,方便的量规选择会导致所有自由度的标量基础,而张量结构仅由现场理论顶点捕获。这提供了一种完全自动化的方法,可以将ADS边界相关器计算为灯芯旋转到Sitter空间后的任何多重性和宇宙波函数系数。

We present for the first time classical multiparticle solutions in Anti de Sitter space (AdS) involving scalars, gluons, and gravitons. They are recursively defined through multiparticle currents which reduce to Berends-Giele currents in the flat space limit. This construction exposes a compact definition of tree-level boundary correlators using a general prescription that removes unphysical boundary contributions. Similarly to the flat space perturbiner, a convenient gauge choice leads to a scalar basis for all degrees of freedom, while the tensor structure is exclusively captured by field theory vertices. This provides a fully automated way to compute AdS boundary correlators to any multiplicity and cosmological wavefunction coefficients after Wick-rotating to de Sitter space.
