摘要：

Multistrange baryon and antibaryon production is suggested to be a useful probe in the search for Quark-Gluon Plasma formation. We report the detection of an OMEGA- +OMEGA-BAR signal in central S+W interactions at 200 A GeV/c and measure the ratio OMEGA-BAR/OMEGA- = 0.57 +/- 0.41 at central rapidity and p(T) > 1.6 GeV/c.
