SUMMARY:John Joseph M. Carrasco (Northwestern\, Saclay)
DESCRIPTION:Loop-Level Double-Copy for Massive Quantum Particles \nI 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.

SUMMARY:Adam Noble (Strathclyde)
DESCRIPTION:Self-forces on a particle interacting with a scalar field\n\nAbstract: The terms “self-force” and “radiation reaction” are often used synonymously\, and while the former is more general\, both can be described by the Lorentz-Abraham-Dirac equation. For a particle accelerating in an electromagnetic field\, radiation reaction is usually the dominant self-force\, but in a scalar field this is not the case. In this talk we explore the subtle interplay between radiation reaction and other self-forces\, and how this can be understood in terms of the dynamical properties of the particle and of the spacetime it inhabits.
