The objective of this project is to construct elements of the ATLAS Phase-II Upgrade for operation at the High-Luminosity Large Hadron Collider (HL-LHC). The increased luminosity delivered, around a factor of 10 more than the will be delivered by 2023, by the HL-LHC to ATLAS will significantly enhance the physics programme. The Large dataset collected will allow ATLAS to make precision studies of the Higgs sector, the Standard Model of particle physics, and to extend the mass scales accessible to searches for signatures of new physics well into the TeV region. This will allow ATLAS to address many of the fundamental questions in particle physics:Is the Higgs mechanism for generating fermion and weak gauge boson masses linked, as is implied by the Standard Model? Does the Higgs mechanism limit the cross-section of vector boson scattering in the Standard Model at high energies, or is there new physics involved in electroweak symmetry breaking?Why is the Higgs boson much lighter than the Planck Mass (the hierarchy problem)?Is there a weakly interacting particle with mass of the order of the electroweak scale that could explain dark matter?Is supersymmetry (SUSY), a symmetry between bosons and fermions, realised in nature?

该项目的目标是构建 ATLAS 第二阶段升级的要素，以便在高光度大型强子对撞机 (HL-LHC) 上运行。 HL-LHC 向 ATLAS 提供的增加的光度大约比 2023 年提供的光度高出 10 倍，这将显着增强物理计划。收集到的大型数据集将使 ATLAS 能够对希格斯扇区（粒子物理的标准模型）进行精确研究，并将可用于搜索新物理特征的质量尺度扩展到 TeV 区域。这将使 ATLAS 能够解决粒子物理学中的许多基本问题：产生费米子和弱规范玻色子质量的希格斯机制是否如标准模型所暗示的那样相互关联？希格斯机制是否限制了高能标准模型中矢量玻色子散射的横截面，或者是否存在新的物理涉及电弱对称性破缺？为什么希格斯玻色子比普朗克质量轻得多（层次结构问题）？是否存在一种质量达到电弱量级的弱相互作用粒子可以解释暗物质？超对称性（SUSY），即玻色子和费米子之间的对称性，在自然界中实现了吗？
