论文摘要
爱丽丝设备包括一个内部跟踪系统，用于在中间范围内进行高精度的顶点和跟踪。多亏了该检测器，在LHC研究的所有碰撞系统中，运行2个数据获得了显着的结果。在此贡献中，突出显示了ITS在此事件中的作用，轨道和二级顶点重建，并报告了轨道冲击参数上的分辨率与数据和蒙特卡洛模拟中碰撞点的比较。最后，列出了依靠出色的爱丽丝顶点和跟踪功能的PP和PB-PB碰撞中获得的一些主要物理结果。
The ALICE apparatus includes an Inner Tracking System for high-precision vertexing and tracking at midrapidity. Thanks to this detector, remarkable results were obtained with Run 2 data in all collision systems studied at the LHC. In this contribution, the role of the ITS in the event, track and secondary vertex reconstruction is highlighted, and the comparison of the resolution on the track impact parameter to the collision point in data and Monte Carlo simulations is reported. Finally, some of the main physics results obtained in pp and Pb--Pb collisions relying on the excellent ALICE vertexing and tracking capabilities are presented.
