Description
It has recently been proposed that collider events can be equipped with a metric, the Energy Mover’s Distance (EMD), which allows one to rephrase multiple aspects of jet physics in a geometric language. Further, the EMD can be exploited to define new observables that measure the distance between a given event and an idealised one. For instance, event isotropy quantifies the resemblance of an event to a uniform energy distribution. We present the first field-theoretical description of the event isotropy distribution. Our calculation includes the all-order resummation of soft and collinear logarithmic contributions at next-to-leading log accuracy, matched to next-to-leading order corrections at fixed order.
