Abstract

We have investigated particle production using a zero degree two-segment focusing beam-line spectrometer, examining 2 x 10¹² Au+Au interactions at a beam momentum of 10.8AGeV/c. We have measured invariant cross sections for protons, various light nuclei (through {ital A}=6), antiprotons, and have set upper limits on the production of heavier nuclei, antideuterons, and strangelets. There is no evidence, within the sensitivity of our measurements, for the formation of new particles having lifetimes >100 ns. copyright 1995 The American Physical Society.
