Abstract

Event-by-event measurement of particle ratios in ultrarelativistic heavy ion collisions was carried out. Using particle identification by dE/dx in the NA49 TPCs, the fluctuations in strangeness production were studied using the ratio of charged kaons to pions. No nonstatistical fluctuations were observed. Further, an upper limit of σ non-stat <4.0% for fluctuations occurring in every event at the 3σ level was deduced.
