摘要

The Monte Carlo generator (LUCIAE) is used to investigate the fluctuations of K/π ratios at super proton synchrotron energies. The distribution of K/π 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.
