Energy Correlations: LHC and Planckian collisions

Since the dawn of quantum physics, high-energy collisions have served as a crucial tool for probing the underlying UV physics. In recent years, energy-energy correlation (EEC) has been appreciated as a collider observable with nice theoretical and phenomenological properties. In this talk, I will give a brief introduction to EEC and related theoretical developments in recent years. In the second part, I will describe interesting aspects of EEC in holographic conformal theories by studying the high-energy gravitational scattering in AdS space. We explore the leading quantum gravity corrections to EEC in the strong coupling limit, based on the properties of high-energy gravitational scattering and unitarization. We find it probes the bulk geometry information of the emergent holographic spacetime and it also exhibits enhancement properties compared with local correlation functions.
