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 at 14 TeV using the LHC at CERN; studies of pbar-p interactions at 2 TeV using the Tevatron at Fermilab; searches for supersymmetric particles, the Higgs boson, and other unobserved forms of matter; precision tests of the 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; R&D work, both of new collider facilities and of measurement tools which can expand the reach of current research.

The Particle Theory Group, part of the Enrico Fermi Institute, carries out research on a wide range of theoretical topics in formal and phenomenological particle physics, including field theory, string theory, supersymmetry, the standard model and beyond, cosmology, and mathematical physics. There are strong ties to the Fermilab Theoretical Physics Group, the Argonne Theoretical High Energy Group, and the High Energy Experiment group at Chicago. Among the many research topics are string theory and unification, duality in gauge theory and string theory, solitons and topological structures, D-branes, non-commutative geometry, the AdS/CFT correspondence, inflationary cosmology, the cosmological constant problem, CP violation, B physics, baryogenesis, supersymmetric model building, precision electroweak measurements, low-energy supersymmetry, heavy quark physics, confinement in QCD, quantum theory of black holes, large extra dimensions, fermion mass hierarchy, and integrable systems.
