摘要：

We report measurements of dBAR, pBAR, K-, and pi- produced at O-degree in collisions of 14.6A GeV/c Si-28 on Al, Cu, and Au targets. A beam-line focusing spectrometer was used to identify particles at rigidities from -2 to -8 GV. The ratio of dBAR/pBAR invariant cross sections at midrapidity (y = 1.7) is (1+/-0.7)x 10(-5), larger than expected from a calculation of ddBAR direct production but smaller than predicted by a simple coalescence model. We also report limits on the production of exotic particles.
