项目摘要

This is a project to carry out fundamental research with the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN. The discovery of the Higgs mechanism at the LHC motivates new questions about the universe: Why is the Higgs boson so light? Is there more than one Higgs Boson particle? Is the Higgs boson produced and does it decay at the rate predicted by the Standard Model of particle physics? Motivated by these questions, this project will include searches for new particles in the Compact Muon Solenoid (CMS) experiment at the LHC. Over the next 7 years, CMS detector components will be replaced to cope with the high radiation environment at the upgraded High Luminosity LHC, which will deliver an extremely high rate of proton-proton collisions. This project also includes contributions to the construction and testing of a new pixel detector, which is both necessary and critical for CMS to perform its physics goals after the upgrade.The high energy physics group at Purdue University Northwest (PNW) focuses their effort on the Forward Pixel detector subsystem for the CMS experiment. After their contributions to the construction of the Forward Pixel detectors, their current thrust is on the assembly and testing of the high luminosity upgrade and assuring the quality of physics datasets to the CMS experiment. Building on the discovery of the Standard Model Higgs boson, the PNW group is also working on searches for new heavy particles that decay to a top quark pair, new spin-2 heavy particles that decay to two Z bosons, and a new search for a new heavy resonance decaying to intermediate resonances. The upgrade of the CMS Forward Pixel detector will require the development of innovative radiation-tolerant technologies, which have the potential to directly enhance the lifespan of detectors used in space research and in medical applications. The PNW group will continue its commitments to undergraduate research, community outreach, K-12 engagement, and teacher training. Through their participation in the LHC upgrades they will engage undergraduate students in detector construction and testing efforts. The PNW QuarkNet center will host an annual Masterclass, where students from local high schools will have the opportunity to visit the university and analyze real CMS data, and an annual K-12 teacher training workshop. Through their research program, courses, and QuarkNet center, they plan to enable the participation of underrepresented groups in physics research, and to inspire and train the next generation of young scientists and engineers.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.

该项目旨在利用欧洲核子研究中心大型强子对撞机 (LHC) 的紧凑型介子螺线管 (CMS) 实验开展基础研究。大型强子对撞机希格斯机制的发现引发了关于宇宙的新问题：为什么希格斯玻色子如此轻？是否存在不止一个希格斯玻色子粒子？希格斯玻色子是否以粒子物理学标准模型预测的速率产生并衰变？受这些问题的推动，该项目将包括在大型强子对撞机的紧凑型介子螺线管（CMS）实验中寻找新粒子。在接下来的7年里，CMS探测器组件将被更换，以应对升级后的高亮度大型强子对撞机的高辐射环境，这将提供极高的质子-质子碰撞率。该项目还包括对新像素探测器的构建和测试的贡献，这对于 CMS 在升级后实现其物理目标既必要又至关重要。普渡大学西北分校 (PNW) 的高能物理小组将工作重点放在 CMS 实验的前向像素探测器子系统上。在为前向像素探测器的构建做出贡献之后，他们目前的重点是高光度升级的组装和测试，并确保 CMS 实验的物理数据集的质量。在发现标准模型希格斯玻色子的基础上，PNW 小组还致力于寻找衰变为顶夸克对的新重粒子、衰变为两个 Z 玻色子的新自旋 2 重粒子，以及衰变为中间共振的新重共振。 CMS前向像素探测器的升级需要开发创新的耐辐射技术，这些技术有可能直接延长空间研究和医疗应用中使用的探测器的使用寿命。 PNW 集团将继续致力于本科生研究、社区外展、K-12 参与和教师培训。通过参与大型强子对撞机升级，他们将让本科生参与探测器的建造和测试工作。 PNW QuarkNet 中心将举办一年一度的大师班，来自当地高中的学生将有机会参观大学并分析真实的 CMS 数据，以及一年一度的 K-12 教师培训研讨会。他们计划通过他们的研究计划、课程和 QuarkNet 中心，让代表性不足的群体参与物理研究，并激励和培训下一代年轻科学家和工程师。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
