High energy physics explores questions about the elementary constituents of matter and energy, the interactions between them, and the nature of space and time. The Office of High Energy Physics (HEP) advances its mission through a program that advances three frontiers of experimental scientific discovery and related efforts in theory while supporting the research and development of enabling technologies. HEP also hosts the Accelerator Stewardship program, which fosters advancements in basic particle accelerator science and technology with broad applicability.
