论文摘要
我们发现，大量标量QCD中的散射幅度可以在循环级别表现出颜色和运动学之间的二元性。具体而言，我们构建了两个不同的大规模标量之间的四点散射的单环积分，以及用Gluonic辐射编码第一个校正到大规模标量散射的五点过程。我们发现，分解和颜色界面二元性是足够的原理，可以完全引导这些计算，从而使我们能够最终从三分树级幅度振幅中构造所有贡献，这些幅度本身完全受对称性的约束。双拷贝构造立即提供了有关所谓的N = 0超级重力理论中大量标量散射的相关预测。
We find that scattering amplitudes in massive scalar QCD can manifest the duality between color and kinematics at loop-level. Specifically we construct the one-loop integrands for four-point scattering between two distinct massive scalars, and the five-point process encoding the first correction to massive scalar scattering with gluonic radiation. We find that factorization and the color-kinematics duality are sufficient principles to entirely bootstrap these calculations, allowing us to construct all contributions ultimately from the three-point tree-level amplitudes which are themselves entirely constrained by symmetry. Double-copy construction immediately provides the associated predictions for massive scalars scattering in the so called N=0 supergravity theory.
