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...

It has been shown recently that defining a jet by a transverse-momentum style resolution parameter produces a fragmentation function that evolves with the standard timelike $\overline{\rm MS}$ DGLAP kernels, to next-to—single logarithmic ($\alpha_s^n L^{n-1}$) accuracy. In contrast the NSL fragmentation function for a purely angular cut like a small jet radius deviates from time-like DGLAP...

Fully hadronic events at hadron colliders are difficult to analyse because extra QCD radiation creates many possible jet combinations and varying jet multiplicities. I will discuss how the two-point correlation spectral function can provide a compact, permutation-invariant event representation for machine-learning analyses. As a benchmark, I apply this method to gluino pair production followed...
