The Space of Collider Events

This event is part of the HEE Seminar Series.

When are two collider events similar? Despite the simplicity of this question, there is no established notion of the distance between pairs of events. In this talk, I propose a metric for the space of collider events based on the earth mover's distance: the "work" required to rearrange the radiation pattern of one event into another. This metric unlocks powerful new tools for analyzing and visualizing data from the LHC.
