Abstract：
We generalize the relativistic Vlasov-Uchling-Uhlenbeck model to include the kaon mean-field potential and the final-state rescatterings of kaons with nucleons,and use it to simulate the subthrcsbold kaon production from the collisions of two Ca nuclci at an incident energy of 1GeV/nucleon. The effects of the vector meanfield potential and the kaon rescattering on the final-state properties of kaons are analyzed. From the calculated results it is found that the effect of repulsive vector potential due to nucleons on the final-state kinetic energy spectrum of kaon is similar to that for the kaon final-state rescattering and leads to an significantly enhanced yield of kaons with large momenta in the laboratory system. However, the effect of the kaon rescattering on its kinetic energy spectrum is reduced considerably by including the repulsive vector potential. This indicates that these final-state interactions of kaons with nucleons are not negligible in order to evaluate reasonably thekaon energy spectrum and angular distribution.
