Abstract
A simple hadronic transport model is proposed for studying the rescattering effect of the pion on the K/π ratio in relativistic nucleus-nucleus collisions. The experimental evidences of evolutionary increase of the K/π ratio from p+p to p+Au and to Si+Au at similar incident energy per nucleon are reproduced reasonably. Experimental results of the K/π ratio at CERN energy (200 GeV/nucleon p+W and S+W) comparable with corresponding results at the Brookhaven Alternating Gradient Synchrotron energy (14.6 GeV/nucleon p+Au and Si+Au) are reproduced as well.Keywords
