High Energy Physics Research

From looking at the products of highly energetic particle collisions at the Large Hadron Collider’s enormous ATLAS detector to measuring the faint signals from the cosmic microwave background at the South Pole, Argonne researchers explore the elementary constituents of matter and energy, the interactions between them, and the ultimate nature of space and time. High Energy Physics Division engages in this research through a program that combines experiment and theory to further scientific discovery, along with a program that advances accelerator technology, instrumentation technology, and cutting-edge scientific computing to enable new breakthroughs.
