论文摘要
对于Run 4，Alice正在开创真正的圆柱跟踪层的构建，这将改善重型风味的Hadron和Dielectrons的测量。此外，正在开发用于测量直接光子的正向热量计（焦点），以访问低$ x $的核子和核的Gluon分布。对于Run 5及以后，提出了Alice 3。它将独特的高分辨率顶点检测器与硅像素跟踪器和现代粒子识别解决方案结合在一起，并在大量的接受度上结合在一起。这将允许具有前所未有的精确度以访问Quark-Gluon等离子体（QGP）的基本属性和动力学的重型流动和二元测量。我们将讨论ITS和焦点的R \＆D结果的升级计划，报告Alice 3的要求和概念。
For Run 4, ALICE is pioneering the construction of truly cylindrical tracking layers, which will improve the measurements of heavy-flavour hadrons and dielectrons. In addition, a Forward Calorimeter (FoCal) for the measurement of direct photons is being developed to access the gluon distributions of nucleons and nuclei at low $x$. For Run 5 and beyond, ALICE 3 is proposed. It combines a unique high-resolution vertex detector with a silicon pixel tracker and modern particle identification solutions over a large acceptance. This will permit heavy-flavour and dielectron measurements with unprecedented precision to access fundamental properties and dynamics of the quark-gluon plasma (QGP). We will discuss the upgrade plans, report on R\&D results for ITS3 and FoCal, and present the requirements and concepts for ALICE 3.
