摘要
本文基于参加者-旁观者模型,用Monte Carlo方法分析了相对论性重离子碰撞中各种次级碰撞对K^+/π^+比值上升的影响。结果表明,仅考虑次级碰撞不足以解释实验观测的K^+/π^+比值上升。
In this paper, the effect of different secondary collisions on the increase of the K^+/π^+ ratio in RHIC is analyzed based on a participant-spectator picture, using Monte Carlo simulation. Our results show that the increase of the K^+/π^+ ratio resulting from the secondary collisions alone is insufficient to explain the experimentally obtained result.
