Abstract
Duringthe on-goingsecond longshutdownof LHC,the forwarddetectorsof theALICEexperiment are implementing an extensive upgrade. In particular, a new Fast Interaction Trigger (FIT) has been designed and built. It consists of three sub-detector systems delivering a broad range of online functionalities, and an essential input for event characterization and physics analysis. For instance, FIT will deliver the precise collision time for the TOF-based particle identification, provide the centrality and the event plane information, and measure the cross section of diffractive processes. This note will discuss usage of FIT in the event plane determination during Run 3. A simulated event plane resolution at √ s NN = 2 . 76 TeV is also presented.
在正在进行的LHC第二次长时间关闭期间，alice实验的前向探测器正在进行广泛的升级。特别地，设计并制造了一种新的快速交互触发器(FIT)。它由三个子探测器系统组成，提供广泛的在线功能，并为事件表征和物理分析提供必要的输入。例如，FIT将为基于tof的粒子识别提供精确的碰撞时间，提供中心性和事件平面信息，并测量衍射过程的横截面。本文将讨论在Run 3期间确定事件平面时FIT的用法。在√s NN = 2时模拟事件平面分辨率。还提出了76tev。
