Production of charged particles identified by a multi cell threshold Čerenkov counter in proton-tungsten and central sulphur-tungsten collisions at 200 GeV/ c per nucleon is discussed. The π ± , p and p 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.

The slope evaluated from the D(N)/D(MT)/(MT**1.5) distribution (denoted as D(N)/D(MT)).
We report measurements of the ratios K+π+, pπ+, K−π−, p¯π−, π−π+, K−K+, and p¯p for hadrons with 0.19

High yields of low-momentum pions were obtained from high-energy primary proton beams. The results are discussed, also with respect to the possibility of setting up cloud muon beams from the very lowmomentum poins produced by 10 GeV/c protons.
