论文摘要
在对美国社区研究粒子物理未来的会议记录的贡献（2021年）中，我们回顾了能量能量相关器（EEC）事件形状在$ E^+E^+E^ - $ nihilation，nihihilation，hadronic碰撞和深层弹性散射中可观察到的最新进展。强调了EEC作为QCD动力学的扰动和非扰动方面的精确探针的重要性。它可用于提取强耦合常数并限制TMD分布函数。密切相关的能量相关形状变量也已用于标记高能量碰撞中产生的增强对象。还强调了在未来电子离子对撞机上研究EEC的机会。
In this contribution to the Proceedings of the US Community Study on the Future of Particle Physics (Snowmass 2021) we review recent progress in the evaluation and application of the Energy-Energy Correlator (EEC) event shape observable in $e^+e^-$ annihilation, hadronic collisions, and deep inelastic scattering. The importance of EEC as a precision probe of the perturbative and non perturbative aspects of QCD dynamics is emphasized. It can be used to extract the strong coupling constant and to constrain TMD distribution functions. Closely related energy-correlation shape variables have also been used to tag boosted objects produced in high energy collisions. The opportunities to study EEC at the future Electron-Ion Collider are also highlighted.
