论文摘要
能量相关器从理论上是QCD动力学的现场清洁和现象学有价值的探针。我们探讨了使用强调腐烂的电动矢量玻色子的能量相关器中编码的信息，以提取其完整的衰减密度矩阵。单点和两点能相关因子的运动学确实可以区分纵向和横向模式，并揭示不同矢量极化之间的干扰模式。这种可观察的物质提高了对微观物理学的敏感性，影响了不同的螺旋度的生产率。在简单的情况下，我们评估对更高维度运算符的影响。
Energy correlators are field-theoretically clean and phenomenologically valuable probes of QCD dynamics. We explore the possibility of using the information encoded in the energy correlators of a hadronically decaying electroweak vector boson in order to extract its full decay density matrix. The kinematics of the one- and two-point energy correlators can indeed discriminate between longitudinal and transverse modes and reveal the interference pattern between different vector polarizations. Such observables improve the sensitivity to microscopic new physics affecting the production rate of the different helicities. We assess the impact on higher dimensional EFT operators in simple scenarios.
