N= 4PDKEEPAAAB中从散射振幅到扩散振幅的Generator

From Scattering Amplitudes to the Dilatation Generator in N=4 SYM

Benjamin I. Zwiebel

摘要:

平面N=4 SYM伸缩生成元的完整自旋链表示早已在一个环中为人所知,其中它涉及引导最近邻2 -> 2相互作用。本文利用超共形对称性,导出了任意大L时,平面伸缩生成元的前导相互作用L -> 2的唯一解。然后,我们建议,这些相互作用是由散射算子,具有N=4 SYM树级散射振幅作为矩阵元素。我们提供了令人信服的证据,这一建议,包括明确检查L= 2,3和超共形对称性的一致性证明。

英文摘要:

The complete spin chain representation of the planar N=4 SYM dilatation generator has long been known at one loop, where it involves leading nearest-neighbor 2 -> 2 interactions. In this work we use superconformal symmetry to derive the unique solution for the leading L -> 2 interactions of the planar dilatation generator for arbitrarily large L. We then propose that these interactions are given by the scattering operator that has N=4 SYM tree-level scattering amplitudes as matrix elements. We provide compelling evidence for this proposal, including explicit checks for L=2,3 and a proof of consistency with superconformal symmetry.
