树级超弦无质量五点振幅的简化

Simplifying the Tree-level Superstring Massless Five-point Amplitude

Carlos R. Mafra

摘要:

我们使用纯旋量形式在树水平上以流线的方式获得超对称无质量五点振幅。我们还证明了弦论中的OPE恒等式与Bern-Carrasco-Johansson五点运动学关系的一个子集的等价性,并证明了其余的BCJ恒等式如何在开弦世界片上从不同的积分区域得出,从而提供了(超对称)BCJ恒等式的第一原理推导。

英文摘要:

We use the pure spinor formalism to obtain the supersymmetric massless five-point amplitude at tree-level in a streamlined fashion. We also prove the equivalence of an OPE identity in string theory with a subset of the Bern-Carrasco-Johansson five-point kinematic relations, and demonstrate how the remaining BCJ identities follow from the different integration regions over the open string world-sheet, therefore providing a first principles derivation of the (supersymmetric) BCJ identities.
