The experimental High Energy Physics group is active in a range of experiments studying the fundamental constituents of matter. The work includes accelerator-based experiments, studies using nuclear reactors, and the detection of new particles from astrophysical sources. This research takes place within the Enrico Fermi Institute and in many cases is joint with faculty in other departments. Faculty also work in close collaboration with researchers at CERN, the Fermi National Accelerator Laboratory and Argonne National Laboratory. The University of Chicago manages the latter two laboratories for the Department of Energy. Current research in high-energy physics includes studies of p-p interactions using the LHC at CERN; searches for weakly interacting and/or long-lived particles at dedicated experiments near accelerators like the LHC; development of new technologies, sensor concepts, collider facilities, and accelerator concepts for future high-energy experiments; searches for supersymmetric particles, dark sectors, and other unobserved forms of matter; precision tests of electroweak theory through measurements of the properties of the top quark and the W and Z bosons; searches for dark matter, both in collider experiments and from astrophysical sources; study of neutrino oscillations; studies of the highest energy cosmic rays; high-precision measurement of CP violation in K decays and high-sensitivity search for rare K decays. - View the experimental particle physics faculty.
