Energy Correlators: From Colliders to the Celestial Sphere and Back
by
Auditorium
DESY
Energy correlators constitute a class of infrared-safe, perturbatively calculable observables originally introduced in the 1970s for precision tests of Quantum Chromodynamics (QCD). In recent years, they have experienced a renaissance due to a rare confluence of advances in formal theory, QCD phenomenology, and collider experiments.
In this talk, I will motivate energy correlators as natural observables at colliders from both theoretical and experimental perspectives. I will present recent phenomenological applications, including high-precision determinations of the strong coupling constant, a novel proposal for a precise top-quark mass measurement, and their use in probing the properties of the quark-gluon plasma. Finally I will discuss recent theoretical developments that deepen our understanding of energy correlators in the small-angle limit, both in the perturbative regime and in the nonperturbative phase following confinement.
We invite you to attend the presentation in person at the DESY Auditorium. We will also offer a webcast to this colloquium.
