Please join us for a seminar featuring two speakers, each presenting for 30 minutes. The related talk is Imaging Boosted Boson Jets with Energy Correlators.
Abstract: Energy correlators have emerged as one of the sharpest tools for probing quantum chromodynamics (QCD), relating asymptotic energy flow directly to the underlying quarks and gluons. In particular, N-point energy correlators (ENCs) in their collinear limit can be measured at both electron-positron and hadron colliders, offering a clean window into jet substructure.
In this talk, I will report the two-loop calculation of ENC jet functions and the resulting collinear resummation at next-to-next-to-leading logarithmic accuracy, across electron-positron annihilation, hadronic Higgs decays and proton-proton collisions. Along the way I will also show the sensitivity of ENCs to the strong coupling constant and leading non-perturbative corrections, demonstrating their power to resolve QCD from partons to hadrons.
