Flat-space structure of gluon and graviton in AdS

Yue-Zhou Li
Dec 2022
摘要
We report the differential representation of three-point and four-pointamplitudes for Yang-Mills fields and Einstein gravity in AdS at tree-level. Theamplitudes exhibit the flat-space structures by using the weight-shiftingoperators with reordering, which make the differential double copy relation atthree-point level straightforward. For four-point Yang-Mills amplitudes, weestablish the differential BCJ relation, which can be useful for proving thedifferential doubly copy at four-point level in the future.
