ALICE (A Large Ion Collider Experiment) - The ALICE Collaboration has built a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. Its aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. The existence of such a phase and its properties are key issues in QCD for the understanding of confinement and of chiral-symmetry restoration. For this purpose, it is carrying out a comprehensive study of the hadrons, electrons, muons and photons produced in the collision of heavy nuclei. ALICE is also studying proton-proton collisions both as a comparison with lead-lead collisions and in physics areas where ALICE is competitive with other LHC experiments. Also see ALICE at CERN.

Argonne Physics Division - The research program in the Physics Division contains studies on the properties of nuclei and atoms. Experiments at the Divisions' heavy-ion accelerator ATLAS study the structure of the nucleus, e.g. the interplay between its tendency to act like a classical liquid drop and its propensity to behave like a microscopic object consisting of a few interacting nucleons or how the nucleus is affected by spinning or heating it. Other experiments at higher-energy accelerators, using more violent collisions with projectiles such as electrons or protons, study the quarks inside the nucleus.

Ernest Rutherford (1871-1937) - Rutherford's works ensure his immortality. As the The New York Times stated, in a eulogy accompanying the announcement of his unexpected and unnecessary death in 1937."It is given to but few men to achieve immortality, still less to achieve Olympian rank, during their own lifetime. Lord Rutherford achieved both. In a generation that witnessed one of the greatest revolutions in the entire history of science he was universally acknowledged as the leading explorer of the vast infinitely complex universe within the atom, a universe that he was first to penetrate."

The experiment will be able to probe new areas by using photoproduction (that is, the scattering of a real photon on a nucleon) to produce exotic states. Also see:

Supersymmetry (SUSY) - A proposed symmetry of nature relating two basic classes of elementary particles: bosons, which have an integer-valued spin, and fermions, which have a half-integer spin. Each particle from one group is associated with a particle from the other, called its superpartner, whose spin differs by a half-integer. In a theory with unbroken supersymmetry each pair of superpartners shares the same mass and internal quantum numbers besides spin, but since no superpartners have been observed yet, supersymmetry must be a spontaneously broken symmetry. The failure of the Large Hadron Collider to find evidence for supersymmetry has led some physicists to suggest that the theory should be abandoned. Also see Introduction to Supersymmetry.
