项目摘要

This award will provide support to a Louisiana Tech University group working on the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, a particle physics laboratory in Geneva, Switzerland. The LHC machine and ATLAS, a large particle detector facility, were built as basic science tools using funds from NSF and other agencies around the world. One of their primary objectives was to find the Higgs Boson, the last particle in the historically successful "Standard Model" (SM) that accounts for so much of the existence of, and forces between, known particles forming the matter in the universe. This effort has been successful. The next step in the experiments is to look for evidence for physics Beyond the Standard Model (BSM) that might, for instance, account for the presence of the mysterious "Dark Matter" that makes up so much of the mass of the universe. The LHC is currently in the midst of Run 2, at almost twice the energy explored earlier and with significantly increased event samples. It is possible that evidence for BSM physics could emerge at this higher energy and with the higher event statistics. Analytically, Louisiana Tech is one of the leading institutions in the US pursuing precision Quantum Chromodynamics (QCD) measurements. In particular, the group applies novel approaches to precision measurements of multi-jet final states. Such studies are significant because the multi-jet ratios that the group measures provide a relatively precise measurement of the strong coupling constant, an important physical quantity, in a manner that ameliorates systematic effects. In addition, any deviations observed in such multi-jet parameters with respect to QCD predictions can provide a window to new physics. In support of their work and other researchers in the field, the Louisiana Tech group has created fast software programs that allow researchers to make fast perturbative QCD predictions of observables in hadronic processes.In the broader context, the LHC provides an excellent platform for providing outreach and communication about basic science to K-12 students and the general public and serves as a recruiting tool for physics majors to Louisiana Tech from the north Louisiana area. As part of this effort, the Louisiana Tech group will partner with local high schools to provide International Masterclasses for physics students that will give them an opportunity to visit the university and its facilities and allow them to perform real analyses using LHC data.This project is jointly funded by the NSF Physics Division Elementary Particle Physics Program and the Established Program to Stimulate Competitive Research (EPSCoR).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.
该奖项将为路易斯安那理工大学的一个小组提供支持,该小组在位于瑞士日内瓦的粒子物理实验室CERN的大型强子对撞机(LHC)上进行ATLAS实验。大型强子对撞机和大型粒子探测器设施ATLAS是利用NSF和世界各地其他机构的资金建造的基础科学工具。他们的主要目标之一是找到希格斯玻色子,这是历史上成功的“标准模型”(SM)中的最后一种粒子,该模型解释了宇宙中形成物质的已知粒子的存在及其之间的作用力。这一努力取得了成功。实验的下一步是寻找超越标准模型(BSM)的物理学证据,例如,可以解释构成宇宙质量的神秘“暗物质”的存在。LHC目前正处于运行2的中期,能量几乎是之前探索的两倍,事件样本也显著增加。BSM物理学的证据可能会在更高的能量和更高的事件统计中出现。从分析上讲,路易斯安那理工大学是美国追求精确量子色动力学(QCD)测量的领先机构之一。特别是,该小组采用新的方法来精确测量多射流的最终状态。这些研究是重要的,因为该小组测量的多射流比提供了一个相对精确的测量强耦合常数,一个重要的物理量,以改善系统的影响。此外,在这种多喷流参数中观察到的任何偏差相对于QCD预测可以提供一个新的物理窗口。 为了支持他们的工作和该领域的其他研究人员,路易斯安那理工大学的研究小组创建了快速软件程序,使研究人员能够对强子过程中的可观测量进行快速微扰QCD预测。大型强子对撞机提供了一个很好的平台,为K-12名学生和公众,并作为一个招聘工具,物理专业的路易斯安那理工大学从路易斯安那州北部地区。作为这项努力一部分,路易斯安那理工大学的研究小组将与当地的高中合作,为物理专业的学生提供国际大师班,让他们有机会参观大学及其设施,并允许他们使用大型强子对撞机的数据进行真实的分析。这个项目是由美国国家科学基金会物理部基本粒子物理计划和刺激竞争性研究的既定计划(EPSCoR)共同资助的该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
