The field of High Energy Physics (HEP) focuses on the study of the fundamental particles that make up the universe and their interactions via the basic forces of nature. It addresses questions such as: Why is there mass? What happened to anti-matter? What is dark matter? What is the nature of the forces that cause particles to interact? We search for answers to these questions using high-energy particle colliders, cosmic rays and neutrinos, ultra-sensitive detectors, and theoretical inquiry.
