J. Phys. G: Nucl. Part. Phys. 30 (2004) S119–S128 Strangeness from 20AGeV to 158AGeV Volker Friese (for the NA49 Collaboration) Particle identification is achieved by the measurements of the specific energy loss dE/dx (resolution ≈4%) in the TPCs and the time-of-flight (resolution ≈60 ps) with the scintillator walls. Depending on their momentum, charged kaons were identified by TOF, combined TOF and dE/dx or dE/dx alone, as figure 1 illustrates. GEANT calculations were used to correct the raw yields for geometrical acceptance, in-flight decay and the efficiency of the time-of-flight system.

Physics Letters B –28 Deuteron production in central PbqPb collisions at 158A GeV NA49 Collaboration S.V. Afanasiev et al. The overall time resolution is about 60–70 ps. The particle identification capability in the experiment is shown in Fig. 1a, where the dErdx value measured in the Main TPC is plotted against the particle mass squared m2 derived from the TOF information. Whereas deuterons would be completely overshadowed by kaons and protons in the dErdx projection, they can be cleanly separated on the basis of the TOF information.
