(Anti)de Sitter空间中树级关联函数的新递归

New recursions for tree-level correlators in (Anti) de Sitter space

Connor Armstrong, Humberto Gomez, Renann Lipinski Jusinskas, Arthur Lipstein, Jiajie Mei

摘要:

我们提出了第一次经典的多粒子解决方案在反德西特空间(AdS)涉及标量,胶子和引力子。它们是通过多粒子电流递归定义的,这些电流在平坦空间极限中减少到Berends-Giele电流。该构造使用移除非物理边界贡献的一般处方公开了树级边界关联函数的紧凑定义。类似于平坦空间微扰,一个方便的规范选择导致所有自由度的标量基,而张量结构只被场论顶点捕获。这提供了一个完全自动化的方法来计算AdS边界关联函数的任何多重性和宇宙学波函数系数后,威克旋转德西特空间。

英文摘要:

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.
