Heavy-flavor quarks are considered to be effective probes of the Quark–Gluon Plasma (QGP) produced in ultra-relativistic heavy-ion collisions. Since quarks have a large mass, their production takes place mostly in initial hard processes, and it is calculable using perturbative QCD. Thus, heavy flavor quarks can be considered as ideal early-generated penetrating probes of the created medium and utilized to investigate mass-dependent properties of in-medium parton energy loss. Moreover, the measurement of heavy-flavor jet production in pp, besides being a natural reference for Pb–Pb studies, allows testing pQCD calculations and models of charm fragmentation in vacuum. In addition, similar measurements in p–Pb collisions allow assessing the importance of cold nuclear matter effects. The ALICE experiment at the LHC has excellent particle tracking capabilities, that allow for a precise jet reconstruction and for the identification of [Formula: see text]-meson and beauty hadron decay vertices, displaced hundreds of micrometers from the primary interaction vertex. In this proceedings, we will report the latest heavy-flavor jet measurements performed in p–Pb and pp collisions.

ALICE 中的重口味喷气机

重味夸克被认为是超相对论重离子碰撞中产生的夸克-胶子等离子体（QGP）的有效探针。由于夸克的质量很大，它们的产生主要发生在初始的硬过程中，并且可以使用微扰 QCD 来计算。因此，重味夸克可以被认为是理想的早期生成的介质中的穿透探针，并用于研究介质中部分子能量损失的质量依赖特性。此外，以 pp 为单位的重味喷射产生的测量，除了作为 Pb-Pb 研究的自然参考之外，还允许在真空中测试 pQCD 计算和魅力碎片模型。此外，在 p-Pb 碰撞中的类似测量可以评估冷核物质效应的重要性。LHC 的 ALICE 实验具有出色的粒子跟踪能力，可以进行精确的射流重建和识别 [公式：见文本]-介子和美强子衰变顶点，从主要相互作用顶点位移数百微米。在本次会议中，我们将报告在 p-Pb 和 pp 碰撞中进行的最新重味喷射测量。
