Description
In recent years, energy correlators have attracted renewed interest as powerful probes of QCD dynamics. Extending this concept to nucleon structure, nucleon energy correlators (NECs) offer a new avenue for imaging partonic dynamics through correlations between initial-state partons and energy flow in the target fragmentation region. In this talk, I will present an investigation of NECs at small $x$ in both the quark and gluon sectors. In particular, we establish a connection between T-odd NECs and the spin-dependent odderon, identifying them as novel probes of C-odd gluon dynamics. We also show that NECs provide a sensitive probe of linearly polarized gluons and saturation effects. Our study establishes NECs as promising observables for exploring small-$x$ dynamics at the future Electron–Ion Collider.
This talk is based on H. Mäntysaari, Y. Tawabutr, X.B. Tong, Phys.Rev.D 112 (2025) 11, 114027 and ongoing work.
