Collaborative Research: S2I2: Cncp: Conceptualization of an S2I2 Institute for High Energy Physics

欧洲核子研究中心的大型强子对撞机等设施代表着在寻求了解大自然的基本构件及其相互作用方面向前迈出的一大步。正如粒子物理标准模型(SM)所预言的那样，希格斯玻色子的发现和非常罕见的B介子衰变的观测，证明了大型强子对撞机实验的强大科学影响。尽管取得了这些成就，但基本的问题仍然存在，包括：为什么自然表达的是SM中体现的对称性，而不是其他对称性？为什么有三代基本的积木(夸克和轻子)？为什么这些积木的群众，无论是在一代人之内，还是在几代人之间，都有如此大的差异？弥漫在宇宙中的暗物质是什么？时空有没有额外的对称性，或者超出了我们已知的三个空间维度？在2020年代升级高亮度大型强子对撞机(HL-LHC)的计划正在顺利进行中。这些升级将导致数据量增加100倍。要利用不断增加的数据量和对升级探测器的大量投资，需要在软件上进行相应的投资，以确保实现科学目标。HL-LHC预计将从10年后开始获取数据，并持续多年。这个概念化项目将为最终的S2I2研究所制定一个战略计划，该计划可以解决HL-LHC时代的软件开发和软件的可持续性挑战。这个概念化项目将支持一系列研讨会，以准备S2I2战略计划，并与国际社会一起，编制一份社区白皮书，为美国和国际软件努力实现HL-LHC的全部科学潜力提供总体路线图。该项目推进了国家战略计算倡议(NSCI)的目标，该倡议旨在维持和加强美国在高性能计算(HPC)研究、开发和部署方面的科学、技术和经济领先地位。该项目得到了计算机与信息科学与工程局的高级网络基础设施部和数学和物理科学局的物理部的支持。

Facilities such as the Large Hadron Collider at CERN represent a huge step forward in the quest to understand the fundamental building blocks of nature, and their interactions. The discovery of the Higgs boson and the observation of very rare B meson decays, as predicted by the Standard Model (SM) of particle physics, demonstrate the strong scientific reach of LHC experiments. Despite these achievements, fundamental questions remain, including: Why does nature express the symmetries embodied in the SM, and not other symmetries? Why are there exactly three generations of basic building blocks (quarks and leptons)? Why are the masses of these building blocks so different from each other, both within a generation and between generations? What is the dark matter which pervades the universe? Does space-time have additional symmetries or extend beyond the three spatial dimensions we know? Planning for upgrades for a High Luminosity LHC (HL-LHC) in the 2020s is well underway. These upgrades will lead to a 100-fold increase in data volume. Exploiting the increased data volume and the large investments in upgraded detectors requires a commensurate investment in software to assure that the scientific goals are achieved.The HL-LHC is expected to take data starting 10 years from now, and continue for many years. This conceptualization project will develop a Strategic Plan for an eventual S2I2 Institute which can address the software development and sustainability challenges of software for the HL-LHC era. This conceptualization project will support a series of workshops to prepare both the S2I2 Strategic Plan and, together with the international community, a Community White Paper providing an overall roadmap for both U.S. and international software efforts to realize the full science potential of the HL-LHC. This project advances the objectives of the National Strategic Computing Initiative (NSCI), an effort aimed at sustaining and enhancing the U.S. scientific, technological, and economic leadership position in High-Performance Computing (HPC) research, development, and deployment.This project is supported by the Division of Advanced Cyberinfrastructure in the Directorate for Computer & Information Science & Engineering and the Physics Division in the Directorate of Mathematical and Physical Sciences.
