AI 中文摘要
我们提出了一个统一框架，用于对深度非弹性散射（DIS）的1-Jettiness类全局事件形状的领头强子化效应进行联合全局分析以实现约束。研究表明，对于逐事件动态确定领头喷注方向的喷注类事件形状子类，领头强子化效应会对硬散射运动学产生非平凡依赖，但这种依赖可明确计算，从而保证1-Jettiness类领头强子化效应的普适性。这种非平凡运动学依赖为同时约束喷注类与DIS thrust事件形状的强子化效应提供了独立的控制变量。该普适性结合运动学控制变量，可将通常被忽略的强子化效应最显著的峰区纳入强耦合常数的精确提取中。我们通过理论预测与模拟数据的对比，论证了对强子化效应采用此类统一处理的必要性。
英文摘要
We propose a unified framework for a combined global analysis to constrain leading hadronization effects across the 1-Jettiness class of global event shapes for Deep Inelastic Scattering (DIS). We show that for the subclass of jet-based event shapes where the leading jet direction is determined dynamically event-by-event, the leading hadronization effects can acquire a non-trivial dependence on the hard scattering kinematics. However, this dependence is explicitly calculable, allowing for universality of leading hadronization effects in the 1-Jettiness class. The non-trivial kinematic dependence provides an independent lever arm for simultaneously constraining hadronization effects in the jet-based and DIS thrust event shapes. This universality, combined with the kinematic lever arm, could allow for including the typically ignored peak region, where hadronization effects are most severe, in precision extractions of the strong coupling. We demonstrate the need for such a unified treatment of hadronization effects through comparisons of theoretical predictions with simulation data.
