论文摘要
在本文中,我们证明了双覆盖框架中的树幅度的因素化,对于各种理论,可以从双重覆盖处方中的重力振幅产生。使用我们的方法,已经得出了用于阳米尔斯理论振幅的分解公式,特殊的杨麦阵型理论和双活动标量理论。差分运算符表示以上理论的因素化之间的某些非平凡关系,可以通过四个角度来理解,这些角度是分解通道,杆结构,量规选择以及BCFW递归。
In this paper, we demonstrate that the factorizations for tree amplitudes in the double-cover framework, for various theories, can be generated from the gravity amplitude in the double-cover prescription. Using our method, the factorized formulae for amplitudes of Yang-Mills theory, special Yang-Mills-scalar theory, and bi-adjoint scalar theory, have been derived. The differential operators indicate some non-trivial relationships among factorizations for above theories, as can be understood through four angles which are factorization channels, pole-structures, gauge choices, as well as BCFW recursions.
