Strangelets and Strange Quark Matter

The properties of finite lumps of strange quark matter (strangelets) with emphasis on the two scenarios of producing strange matter in relativistic heavy ion collisions are summarized. As an outlook, the possibility of short-lived strange composites and charmed matter are discussed for coming heavy ion experiments.Comment: 8 pages, 3 figures, uses elsevier style and epsf.sty, invited talk given at the International Conference on Hypernuclear and Strange Particle Physics (HYP'97), October 13-18, Brookhaven National Laboratory, USA, to be published in Nuclear Physics
