摘要

在强子对撞中研究重味介子和重子,可以深入了解大粒子密度中重夸克强子化的特性,在这里可能会出现真空中碎片之外的新机制。研究不同对撞系统和事件倍率下的重味产生提供了有关多粒子相互作用以及高倍率pp和pp-Pb对撞中强相互作用介质发展的信息。在Pb-Pb对撞中,对粲和美强子的核调制因子($R_{\rm AA}$)的测量为描述夸克-胶子等离子体(QGP)中重夸克的介质能量损失提供了一种方法。此外,对重夸克的椭圆流($v_{2}$)的测量也有助于深入了解重夸克的扩散及其参与夸克-胶子等离子体集体运动的情况。本文将介绍利用 ALICE 探测器测量到的粲和美粒子产生的最新结果。

Recent heavy-flavour measurements from ALICE
Studying heavy-flavour mesons and baryons in hadronic collisions provides unique insights into the properties of heavy-quark hadronisation amid large partonic densities, where novel mechanisms beyond in-vacuum fragmentation may emerge. Examining heavy-flavour production across different collision systems and event multiplicities provides information about multi-parton interactions and the development of a strongly-interacting medium in high-multiplicity pp and p-Pb collisions. In Pb-Pb collisions, measurements of the nuclear modification factor ($R_{\rm AA}$) for charm and beauty hadrons provide a means to characterise the in-medium energy loss of heavy quarks in the quark-gluon plasma (QGP). In addition, measurements of the elliptic flow ($v_{2}$) for heavy quarks provide insights into their diffusion and their participation in the collective motion of the QGP. In this contribution, recent results of charm and beauty production measured with the ALICE detector are presented.
