AI 中文摘要
重味喷注及其子结构为研究夸克质量在量子色动力学（QCD）辐射中的作用，以及其在核物质中的修正提供了独特视角。本研究探讨对质量效应敏感的重夸克能量-能量关联器（EEC），重点关注角分布、能量流和死锥效应。我们证明粲夸克和底夸克的有限质量如何重塑喷注内辐射模式，导致小角度处出现特征性抑制，且与无质量喷注的预期存在可测量偏差。通过有效场论分析，我们将这些可观测量的计算扩展到含原子核的反应中，表明介质诱导辐射与真空质量抑制相互竞争，导致喷注子结构发生非平凡修正。具体而言，我们确定了EEC由重夸克质量主导的区域，该区域中此可观测量在QCD物质中表现出定性和定量的不同行为。我们讨论了与原子核反应中粲夸克和底夸克能量-能量关联器的修正，并进一步证明该形式体系可在当前设施的小碰撞系统中进行测试。
英文摘要
Heavy-flavor jets and their substructure provide a unique window into the role of quark mass on QCD radiation and its modification in nuclear matter. In this work, we investigate heavy-quark energy-energy correlators (EECs) that are explicitly sensitive to mass effects, focusing on angular distributions, energy flow, and the dead-cone effect. We demonstrate how the finite mass of charm and bottom quarks reshapes the intra-jet radiation pattern, leading to characteristic suppression at small angles and measurable deviations from massless jet expectations. Using effective field theory analysis, we extend the calculation of these observables to reactions with nuclei to show that medium-induced radiation competes with vacuum mass suppression, resulting in a nontrivial modification of jet substructure. Specifically, we identify regimes where EECs are dominated by the heavy quark mass, leading to qualitatively and quantitatively different behavior of this observable in QCD matter. We discuss the charm and bottom jet energy-energy correlators modification in reactions with nuclei, and further demonstrate how the formalism can be tested in small collision system at current facilities.
