Elementary particle physics reflects the human quest to understand the basic building blocks of nature and the rules that govern the physical world. This quest has led not only to critical scientific advancements and technology breakthroughs, but also to the development of essential technologies enabling new medical treatments, productive techniques in manufacturing, and enhanced capabilities in quantum computing, as well as ancillary benefits such as the precursor to the World Wide Web, which was created to manage the enormous data flows at CERN.At the request of the Department of Energy and the National Science Foundation, this report explores long-term goals and future ambitions for particle physics. Elementary Particle Physics: The Higgs and Beyond presents a bold 40-year vision for the field and highlights critical actions necessary to make this vision reality. The recommendations of this report will guide support and investments to maintain U.S. leadership in particle physics and move the field forward.
