| Abstract | A non-monotonic energy dependence of the K**+/pi**+ ratio with a sharp maximum close to 30 A GeV was observed in central Pb+Pb collisions. It was suggested that the kinematic freeze-out of omega takes place directly at QGP hadronization. The NA49 detector, a large acceptance hadron spectrometer at the CERN SPS, consisting of four TCPs was also discussed. The ionization energy loss (dE/dx) measurements in the two Main TPCs (MTPC), which were outside the magnetic field, were used for mass determination. (Edited abstract) 12 Refs. |
