Popis:	We discuss an investigation of negative particle production in interactions of 14.6 A GeV/c 28Si with targets of Al, Cu, and Au at the Brookhaven National Laboratory AGS, experiment E858. The experiment was performed using a beamline spectrometer to measure cross sections for meta-stable negatively charged particles produced at 0° at rigidities from 2 GV to 8 GV. We report upper limits on the production of new particles in the mass to charge (A/Z) range from −1 to −6 and discuss a simple model for describing our sensitivity.
