| Abstract | The Monte Carlo generator (LUCIAE) is used to investigate the fluctuations of K/ pi ratios at Super Proton Synchrotron energies. The distribution of K/ pi ratios seems to be Gaussian from the simulation and the distribution width, and the relative variances are larger than those from the Poissonian-type pure-statistical fluctuations. This discrepancy might be attributed to the dynamical fluctuations involved in the LUCIAE model. (8 refs). |
