“From particle scattering to the mysteries of black holes”
When speaking of black holes, we often invoke the no hair theorem, which states that a black hole is characterized by three quantum numbers, the mass, charge and spin. These are precisely the quantum numbers associated with a particle. We will explore how to think about the interaction of massive particles in a purely on-shell fashion, allowing us to establish a kinematic notion of “minimal coupling”. Remarkably, we will demonstrate that such minimal couplings can be mapped to all known four-dimensional black hole solutions, and in the process revealing remarkable hidden properties of black holes.
