项目摘要

The Standard Model (SM) of particle physics has been a successful theory, explaining experimental observations involving weak, electromagnetic, and strong interactions over the last few decades. However, as experiments probe deeper with increasing energies, it is evident that the SM is an incomplete theory: it fails to account for the mass of neutrinos and does not explain astronomical dark matter (DM). As members of the Compact Muon Solenoid (CMS) Collaboration, the Vanderbilt group exploits the rich particle physics program at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. The LHC, the premier particle accelerator operating at the CERN laboratory, is expected to significantly expand the realm of discoverable BSM physics signatures, leveraging the synergy between particle physics and cosmology. This work will probe BSM particles with TeV scale masses, such as the so-called Z-prime/W-prime bosons and leptoquarks, by targeting their production at the LHC by considering new and rare mechanisms involving non-universal couplings to the SM fermions. This research could potentially shed light on important questions in physics, such as the particle nature of DM, the evolution and structure of our universe, and the anomalies in precision measurements of the B-meson branching ratios and the muon anomalous magnetic moment, which show deviations of more than three standard deviations from the SM expectation. The physics goals are to search for new physics, to improve the algorithms for the reconstruction and identification of third generation fermion particles, and to contribute to hardware activities of the pixel detectors and pixel luminosity telescope, including the luminosity measurement of CMS.This project will also address the underrepresentation of women and minorities in particle physics through a partnership with Fisk University, a Historically Black University near Vanderbilt University. The plan includes a formal network of peer-to-peer mentoring via research experiences that are integrated with the group’s research program. These experiences will be individually tailored to each participating URM student transitioning from their undergraduate studies into the Fisk-Vanderbilt Bridge Program and will provide opportunities to the Bridge students to engage in particle physics research and interact with scientists in other fields to tackle cross-disciplinary issues. In addition, this project will also hold a yearly summer school for URM high school juniors and seniors from the local community and surrounding suburbs who are transitioning into their post-secondary college education.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.

粒子物理的标准模型(SM)是一个成功的理论，它解释了过去几十年中涉及弱相互作用、电磁相互作用和强相互作用的实验观测。然而，随着实验的深入，随着能量的增加，SM显然是一个不完整的理论：它无法解释中微子的质量，也无法解释天文暗物质(DM)。作为紧凑型Muon螺线管(CMS)合作的成员，Vanderbilt小组利用瑞士日内瓦CERN的大型强子对撞机(LHC)的丰富粒子物理计划。大型强子对撞机是欧洲核子研究中心实验室运行的首屈一指的粒子加速器，预计将利用粒子物理学和宇宙学之间的协同作用，显著扩大可发现的BSM物理特征的领域。这项工作将探索具有TeV尺度质量的BSM粒子，如所谓的Z-素数/W-素数玻色子和轻夸克，通过考虑涉及到SM费米子的非万能耦合的新的和罕见的机制，将它们的产生指向LHC。这项研究可能会揭示物理中的重要问题，如DM的粒子性质，我们宇宙的演化和结构，以及B介子分支比和介子反常磁矩的精确测量中的异常，这些异常显示出与SM预期的三个以上的标准偏差。物理目标是寻找新的物理，改进重建和识别第三代费米子粒子的算法，并促进像素探测器和像素光度望远镜的硬件活动，包括CMS的光度测量。该项目还将通过与Fisk大学的伙伴关系解决妇女和少数族裔在粒子物理学中代表性不足的问题，Fisk大学是范德比尔特大学附近的历史上的黑人大学。该计划包括一个正式的对等指导网络，通过与该组织的研究计划相结合的研究经验进行指导。这些体验将为每个参与的URM学生从本科过渡到Fisk-Vanderbilt Bridge计划而量身定做，并将为Bridge的学生提供参与粒子物理研究的机会，并与其他领域的科学家互动，以解决跨学科问题。此外，该项目还将为来自当地社区和周边郊区的URM高中三年级和四年级学生举办一年一度的暑期学校，这些学生正在过渡到他们的专上大学教育。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
