Antibaryon production in sulphur nucleus collisions at 200 GeV per
nucleon

Αγγλικά

Antiproton production near midrapidity has been studied in central
collisions of S-32 With sulphur, silver and gold nuclei at 200 GeV per
nucleon. The measured transverse mass distributions can be described by
an exponential with inverse slope parameters of about 200 MeV, similar
to those obtained from <(Lambda)over bar> spectra. The rapidity density
increases weakly with the target mass, ranging from 0.4 to 0.7. The
ratio <(Lambda)/(p)over bar> near midrapidity is approximately 1.4 on
average, significantly larger than the corresponding ratio observed in
proton-proton and proton-nucleus collisions.
