论文摘要
我们在（a）ds $ _ {D+1} $中介绍了Gluon和Graviton三分函数之间的微分双拷贝关系。我们在（a）ds中介绍了一组差分运算符，它们自然地概括了在平面空间中散射幅度的壳运动学。这提供了一种通过相应的差分运算符替换振幅的运动学变量来构建（a）DS相关器的方法，并适当订购它们。通过构造，所得的相关器显然是形式不变的，具有正确的平整限制，并且具有差异的双层拷贝结构。
We present differential double-copy relations between gluon and graviton three-point functions in (A)dS$_{d+1}$. We introduce a set of differential operators in (A)dS that naturally generalize on-shell kinematics of scattering amplitudes in flat space. This provides a way to construct (A)dS correlators by replacing the kinematic variables of amplitudes with the corresponding differential operators and suitably ordering them. By construction, the resulting correlators are manifestly conformally invariant, with the correct flat-space limit, and exhibit a differential double-copy structure.
