Loop-Level Double-Copy for Massive Quantum Particles

I will discuss arXiv:2010.13435. We will review recent breakthroughs in understanding some general features of relativistic Quantum Field Theory and associated structure in physical prediction, such as color-dual double-copy and specifically how we can apply it when we have massive scalars in arbitrary representations. We will use factorization and the color-kinematics duality to bootstrap amplitudes at tree and loop-level in massive scalar QCD. Specifically, we construct the one-loop integrands for scattering between two distinct massive scalars at four-points and the related five-points correction with emitted gluon, and thus the associated gravitational amplitudes in the so called N=0 supergravity theory.
