Research in Elementary Particle Physics

这项提议要求继续支持密歇根州立大学(MSU)BROCK/Abolins小组在实验基本粒子物理方面的研究计划，该计划主要基于费米实验室Tevatron对撞机的D0实验和CERN大型强子对撞机(LHC)的ATLAS实验。在过去的几十年里，物理学家已经能够越来越详细地描述组成宇宙的基本粒子以及它们之间的相互作用。这一成功在很大程度上要归功于费米实验室的Tevatron计划，D0和CDF做出了重大贡献。这个MSU小组在D0实验的建设和提出的物理问题方面做出了重大贡献，并发挥了许多领导作用。目前，该小组正在研究单顶夸克的产生机制，该机制对标准模型以外可能出现的新物理很敏感。它参与了生产率的初步测量，许多人认为这是Tevatron计划取得的最重要的结果。与此同时，大型强子对撞机和ATLAS将开始在新的能量和光度制度下运行，在发现和测量方面拥有更大的希望，这将导致我们对世界是如何构成的，以及管理其运行的定律的性质的看法的修订。该小组现在正在过渡到ATLAS计划，在该计划中，他们将利用其在单顶物理方面的丰富经验，在类似的研究以及其他领域发挥领导作用，如构建触发算法和安装触发支持硬件及其支持基础设施。此外，密歇根州立大学和密歇根大学正在建设一个新的二级计算中心，教职员工的研究工作将部分针对该设施的管理和使用。在更广泛的影响下，该小组将主要在QuarkNet计划内继续工作，以及在夏季学期为科学和数学教育部开设一门现代物理课程，重点是初级粒子物理和宇宙学，以及一门创新的非科学学生荣誉课程，该课程通常吸引约20名高中教师。计划在密歇根州立大学的中庭举办与ATLAS计划相关的科学日和永久展览。

This proposal requests continuing support for a program of research for the Brock/Abolins group at Michigan State University (MSU) in experimental elementary particle physics based primarily on the D0 experiment at the Fermilab Tevatron collider and the ATLAS experiment at the Large Hadron Collider (LHC) at CERN.For the past few decades, physicists have been able to describe with increasing detail the fundamental particles that make up the Universe and the interactions between them. Much of this success has been due to the Tevatron program at Fermilab with D0 and CDF making major contributions.. This MSU group has made major contributions to the D0 experiment in its construction and in the physics questions proposed as well as in many leadership roles. Currently, the group is investigating the single top quark production mechanism which is sensitive to possibly new physics beyond the Standard Model. It participated in the initial measurements of the production rate a measurement many consider the single most important result from the Tevatron program. At the same time the LHC and ATLAS will start operation in new regimes of energy and luminosity holding even greater promise for discoveries and measurements leading to revisions of our views on how the world is constructed and the nature of the laws that govern its operation. This group is now transitioning into the ATLAS program where it will parlay its wealth of experience in single top physics into a leadership role in a similar study as well as other areas such as construction of trigger algorithms and installing trigger supporting hardware and its supporting infrastructure. In addition, MSU and the University of Michigan are building a new Tier 2 computing center and faculty research efforts will be directed in part to management and usage of this facility.On Broader Impacts, the group will continue its work primarily within the QuarkNet program as well as an innovative non-science student honors course emphasizing Elementary Particle Physics and Cosmology and a course on modern physics for the Division of Science and Math Education during the summer term which typically draws ~20 high school teachers. Science Days and permanent exhibits in an atrium setting at MSU related to the ATLAS program are planned.
