Exotica searches in heavy ion collisions---past and future
- University of California, Space Sciences Laboratory, Berkeley, California 94720 (United States)
The large energy and particle densities achieved in relativistic nucleus-nucleus collisions provide an environment conducive to formation of new types of particles or new states of matter. The environment differs from that of high energy elementary particle collisions primarily in the number density of nearest neighbor hadrons and, if a plasma state is formed, nearby quarks and gluons as well. In the chaos of hadronization, new composite particles may emerge. If a plasma has been achieved, free roaming quarks may not locate their color singlet partners and thus may emerge as naked particles. The experimental challenge is to identify these new particles and states, even though they may be very short-lived, in the presence of the large ``normal`` hadron particle backgrounds. This paper describes some of the most sensitive searches for new particles performed to date and gives the status of some experiments planned for the near future. Although programs at CERN are mentioned, the emphasis is on the programs at the AGS and RHIC. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
