用量子分子动力学(QMD)模型研究了中能重离子碰撞中的K+介子流. 计算结果显出, 实验数据只能与计入由手征拉格朗日导出的K+平均场势的结果相符合.这表明, K+介子边流的形式是对在核介质中K+位势的一个有效的探针.

The kaon flow in heavy-ion collisions at intermediate energy is studied in the QMD model. The calculated results show that the experimental data are only consistent with the ones that include the kaon mean-field potential from the chiral Lagrangian.This indicates that the sideflow pattern of positive charged kaons is an useful probe of the kaon potential in nuclear medium.
