Abstract: The Energy-Energy Correlator (EEC) measures the energy-weighted two-particle angular correlations in high-energy colliders. In recent years, there has been a resurgence of interest in the EEC as a theoretical and experimental tool for exploring the phenomena of the Perturbative Regge trajectory in QCD, which governs the evolution of parton distributions and fragmentation functions. In this talk, I will give an overview of the EEC program, both theoretically and experimentally. I will highlight a number of its advantages over traditional QCD jet observables, including its correlation function representation, the use of conformal symmetry and Operator Product Expansion (OPE).

Bio: HuaXing Zhu is an Associate Professor at the School of Physics, Peking University. He obtained his PhD degree in 2012 from Peking University. Since then, he has been a postdoctoral fellow at SLAC National Accelerator Laboratory and the Center for Theoretical Physics at MIT. He held a tenured-track researcher position at Zhejiang University from 2017 to 2023 before moving to Peking University. His research interests involve quantum field theory and particle physics, with a particular focus on the development of theoretical tools for studying the strong interactions of quarks and gluons in quantum chromodynamics. He is the recipient of the 2020 Qiushi Outstanding Scholar Award and the 2023 Asian Young Scholar fellowship.
