Résumé |
In this talk, I explain how various concepts and techniques in quantum field
theory and collider physics can be naturally translated into a new geometric
language. Using the energy mover's distance, which quantifies the minimal amount
of "work" required to rearrange one event into another, we can define a distance
between pairs of collider events. This distance can then be used to triangulate
the "space" of collider events and rigorously define various geometric objects.
Many well-known collider observables, jet algorithms, and pileup mitigation
schemes have a simple geometric interpretation, as does the important concept of
infrared and collinear safety. Intriguingly, these ideas can be lifted from a
distance between events into a distance between theories, with potential relevance
for visualizing and interpreting data from the LHC. |
