项目摘要

The objective of this project is to lead the construction of the Pixel detector for 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 2026 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?The Pixel detector system is at the centre of the ATLAS experiment and provides crucial information for the analysis of data. The detector takes a photograph of the event and measures the momenta of the particles produced. It associates the particles from the interesting high energy events to a single vertex and can also identify longer lived particles such as b-quarks from the displaced vertices.

该项目的目的是领导Atlas II期升级的像素检测器的构建，用于在高亮度大型强调撞机（HL-LHC）上运行。提供的发光度增加了，比2026年将HL-LHC交付的亮度大约要多10倍，将显着增强物理计划。收集的大型数据集将允许Atlas对Higgs部门，粒子物理的标准模型进行精确研究，并扩展可访问质量尺度以搜索新物理学的签名到TEV区域。这将允许地图集解决粒子物理学中的许多基本问题：HIGGS机制是否为链接的HIGGS机制和弱尺度玻色子质量产生，正如标准模型所暗示的吗？ 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在本质上实现的玻色子和费米子？像素探测器系统是Atlas实验的中心，并提供了至关重要的信息以进行数据分析。检测器拍摄事件的照片，并测量产生的颗粒的动量。它将颗粒从有趣的高能事件与单个顶点相关联，还可以识别出更长的寿命颗粒，例如来自位移的顶点的B Quarks。
