This project is devoted to research using ATLAS, a multi-purpose particle physics detector situated around the 27 km ring of the Large Hadron Collider (LHC) located at CERN, the European particle physics laboratory near Geneva, Switzerland. The goal of the project is to explore the fundamental nature of the universe in order to understand its evolution from the hot, dense soup of energy and matter existing soon after the Big Bang to the cool, diffuse universe we see today. The interactions and evolution of the fundamental constituents of the universe are well described by the Standard Model (SM) of Particle Physics that has been very successful in predicting the behavior of nature in the currently available energy regimes. The search for physics Beyond the SM (BSM) has been the focus of physicists since the discovery of the Higgs boson. The work of this award will contribute to the BSM search by exploring production mechanisms of the Higgs boson. In addition, the award will help construct the ongoing upgrade to the ATLAS detector as it prepares for the High-Luminosity upgrade to the LHC accelerator itself (HL-HLC).In this research award the California State University group will probe the SM by examining events which produce pairs of Higgs bosons. The aim is to measure the self-coupling of the Higgs boson, thought to be a sensitive probe of BSM. Technically, the CSU ATLAS group will work as members of the ATLAS Inner Tracker Upgrade (ITk) as part of the HL-LHC project. The ITk will be a crucial component of future ATLAS discoveries in the Higgs sector when the LHC upgrade is complete around 2026. This award will continue the CalState program of building the future workforce by providing training to the diverse students of the system, with hands-on work on the cutting-edge high energy physics program of ATLAS.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目用于使用Atlas进行研究，Atlas是一个多功能粒子物理探测器，位于位于瑞士日内瓦附近的欧洲粒子物理实验室Cern的大型强子撞机（LHC）的27公里环（LHC）附近。该项目的目的是探索宇宙的基本性质，以了解其从大爆炸之后不久的热量汤到我们今天看到的凉爽，散射的宇宙之后不久存在的。粒子物理学的标准模型（SM）很好地描述了宇宙基本成分的相互作用和演变，这些模型在预测当前可用的能源方案中的自然行为方面非常成功。自发现Higgs Boson以来，对SM（BSM）以外的物理学的搜索一直是物理学家的重点。该奖项的工作将通过探索Higgs Boson的生产机制来为BSM搜索做出贡献。此外，该奖项将有助于对ATLAS探测器进行持续的升级，因为它为LHC加速器本身（HL-HLC）的高光度升级做准备。在该研究奖中，加利福尼亚州立大学小组将通过检查HIGGS Bosons对的事件来调查SM。目的是测量希格斯玻色子的自我耦合，被认为是BSM的敏感探针。从技术上讲，作为HL-LHC项目的一部分，CSU Atlas集团将担任Atlas Inner Tracker升级（ITK）的成员。 当LHC升级完成时，ITK将是Higgs领域未来地图集发现的重要组成部分基金会的智力优点和更广泛的影响评论标准。
