The Hidden Geometry of Particle Collisions

by Dr Patrick Komiske (MIT)

Thursday 4 Jun 2020, 15:30 → 16:30 Europe/Rome

google meet (on-line)

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.
