Inhaltszusammenfassung
The production of A, A and Ks~ has been stud- ied in 200 GeV/nucleon p + S and S + S collisions in the streamer chamber of the NA35 experiment at the CERN SPS. Significant enhancement of the multiplicities of all observed strange particles relative to negative hadrons was observed in central S+S collisions, as compared to p+p and p+S collisions. The latter collisions show no overall (relative) strangeness enhancement over p + p, but the rapidity distributions and hadron multiplicities indicat...The production of A, A and Ks~ has been stud- ied in 200 GeV/nucleon p + S and S + S collisions in the streamer chamber of the NA35 experiment at the CERN SPS. Significant enhancement of the multiplicities of all observed strange particles relative to negative hadrons was observed in central S+S collisions, as compared to p+p and p+S collisions. The latter collisions show no overall (relative) strangeness enhancement over p + p, but the rapidity distributions and hadron multiplicities indicate some secondary cascading production of A par- ticles in the p + S and p + Au collisions. The A polariza- tion in central S+ S collisions was found to be compati- ble with zero up to Pr = 2 GeV/c.» weiterlesen» einklappen
