In this talk, I will discuss recent developments in collider physics towards identifying and utilizing a “hidden” geometry of particle collisions. Building off the recently introduced Energy Mover’s Distance (EMD), I will endow the space of events with a metric, which will enable more complicated geometric primitives, such as N-particle manifolds, to be described. Using these tools, I will show how numerous aspects of the modern theoretical and experimental collider program can be naturally understood in this geometric language, including infrared singularities, Sudakov safety, event and jet substructure observables, jet clustering, pileup mitigation, and more. I will conclude by discussing how these ideas can be bootstrapped in order to provide
insight into the geometry of the space of theories.
