论文摘要
我们显示了雅各比身份的几种不同测试的等效性,即在树级处的天体电流,特别是在任何EFT中的硬动量空间4点振幅上找到了一个简单,实用的条件。一路上,我们阐明了软插入雅各比的软和界线限制顺序的作用,我们认为,尽管具有当前的代数式特性,但本文中提出的软插入不能解释为天体共同场理论中的本地操作员。
We show the equivalence of several different tests of the Jacobi identity for celestial currents at tree level, in particular finding a simple, practical condition on hard momentum space 4-point amplitudes in any EFT. Along the way we clarify the role of the order of soft and collinear limits in obstructing Jacobi for soft insertions and we argue that, despite their current-algebra-like properties, soft insertions as formulated in this paper cannot be interpreted as local operators in celestial conformal field theory.
