High Energy Physics (HEP) explores what the world is made of and how it works at the smallest and largest scales, seeking new discoveries from the tiniest particles to the outer reaches of space. This quest inspires young minds, trains an expert workforce, and drives innovation that improves the nation’s health, wealth, and security.

Our research is inspired by some of the biggest questions about our universe. What is it made of? What forces govern it? How did become the way it is today? Finding these answers requires the combined efforts some of the largest scientific collaborations in the world, using some of the most sensitive detectors in the world, at some of the largest scientific machines in the world.

We support U.S. researchers that play leading roles in these international efforts and world-leading facilities at our National Laboratories that make this science possible. We also develop new accelerator, detector, and computational tools to open new doors to discovery science, and through Accelerator Stewardship, work to make transformational accelerator technology widely available to science and industry.
