Pion and proton production in proton-tungsten and sulphur-tungsten interactions at 200 GeV/c per nucleon

摘要

Production of charged particles identified by a multi cell threshold Cerenkov counter in proton-tungsten and central sulphur-tungsten collisions at 200 GeV/c per nucleon is discussed. The pi(+/-), p and (p) over bar production ratios and transverse mass spectra at central rapidity and p(T) > 0.6 GeV/c are presented and compared with results from other experiments at the same beam energy.
