Particle Physics at the High Energy Frontier: Run-3 to HL-LHC

这个研究项目旨在通过探索自然的基本对称性及其与质量起源的关系，在最小的尺度上更好地理解宇宙。2012年，一个质量接近125GeV的希格斯玻色子的发现，既代表了粒子物理标准模型的最高成就，也是一个超越它的暗示--如果没有新的、未被发现的物理学，一个轻的希格斯玻色子如何可能在巨大的、不稳定的量子效应中生存下来？此外，从天文观测中已知暗物质的存在；然而，暗物质的粒子性质仍然笼罩在神秘的阴影中。康奈尔大学小组的联合活动解决了这些困扰科学的基本问题--暗物质的质量起源和粒子性质--并有可能出现令人惊讶的发现，可能会改变我们理解物理世界的方式。这项奖励将支持康奈尔大学在欧洲核子研究中心(CERN)的大型强子对撞机(LHC)上进行的CMS实验，这是一个位于瑞士日内瓦的粒子物理实验室。在本合同的三年期限内，CMS将完成仪器升级并恢复数据采集。此外，在此期间，用于高亮度HL-LHC运行的CMS的升级将全速进行。康奈尔大学的小组是美国小组在CMS上更广泛的HL-LHC努力的项目负责人，并有自己的特殊兴趣，包括升级前向像素跟踪探测器和实验的跟踪触发。在康奈尔小组显著的更广泛的影响活动中，许多活动包括通过康奈尔基于加速器的科学和教育实验室(CLASSE)的外联办公室向纽约州北部地区的学生和公众进行重大外联。该集团将开发大量的教学单元和科学工具包，用于“借阅图书馆”，可以带到学校或用于课外项目，为当地数百名儿童带来令人兴奋的动手活动。为支持这类活动而对教师进行培训的要求远远超过培训机会的提供。为了扩大这一有价值的计划的影响范围，康奈尔大学的团队将制作视频，进一步扩大可用于支持借阅图书馆的材料。这项工作和内容的开发将与CLASSE专业人员密切协调，以确定主题、长度和目标受众。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。

This research project aims to better understand the Universe at the smallest scales by probing nature's basic symmetries and their relation to the origin of mass. The 2012 discovery of a Higgs boson with mass close to 125 GeV represents both the crowning achievement of the Standard Model of particle physics and a hint beyond it - how can a light Higgs boson possibly survive huge, destabilizing quantum effects without new, undiscovered physics? Furthermore, dark matter is known to exist from astronomical observations; however, the particle properties of dark matter remain shrouded in mystery. The combined activities of the Cornell University group address such basic questions puzzling science - the origin of mass and the particle nature of dark matter - and have the potential for surprising discoveries that may change the way we understand our physical world. This award will provide support Cornell's work on the CMS experiment at the Large Hadron Collider (LHC) at CERN, a particle physics laboratory in Geneva, Switzerland. During the three-year timeframe of this award, CMS will complete instrumentation upgrades and resume data taking. Additionally during this period, the upgrades of CMS for high luminosity HL-LHC operation will be in full gear. The Cornell group serves as a project leader of the broader HL-LHC effort of the US groups on CMS, and has its own specific interests, including in the upgrade of the forward pixel tracking detector and track-triggering for the experiment. Among the notable broader impacts activities of the Cornell group, many include significant outreach to students and the public in the upstate New York region through the outreach office of the Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE). The group will develop a significant number of teaching units and science kits for a "Lending Library" that can be taken to schools or used in after-school programs to bring exciting hands-on activities to hundreds of local children. The requests for teacher training in support of such activities have far outnumbered the availability of training opportunities. To increase the reach of this valuable program, the Cornell group will produce videos to further expand upon the materials that are available to support the Lending Library. This work and content development will be done in close coordination with the CLASSE professional staff, to identify topic, length and target audience.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.
