规范理论振幅的极小基

Minimal Basis for Gauge Theory Amplitudes

N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Pierre Vanhove

摘要:

利用弦论中基于单值积分的恒等式导出玻色和超对称弦论中不同色序树能级振幅之间的关系。这些关系意味着色序树层次n点规范理论振幅可以在(n-3)的最小基上展开!振幅这一结果适用于任何选择的极化的外部状态和在任何数量的维度。

英文摘要:

Identities based on monodromy for integrations in string theory are used to derive relations between different color ordered tree-level amplitudes in both bosonic and supersymmetric string theory. These relations imply that the color ordered tree-level n-point gauge theory amplitudes can be expanded in a minimal basis of (n-3)! amplitudes. This result holds for any choice of polarizations of the external states and in any number of dimensions.
