标题： Clocking hadronization in relativistic heavy ion collisions with balance functions

摘要： 在相对论重离子碰撞的初始阶段，假设了一种新的物质状态的存在，直到反应开始后的几飞秒/厘米才出现正常的强子。 为了验证这一假设，利用平衡函数评估了电荷与其相应反电荷之间的关联。 研究表明，当以相对快速度作为函数测量时，晚期强子化的特点是电荷/反电荷对的高度关联。 显示英文摘要

摘要： A novel state of matter has been hypothesized to exist during the early stage of relativistic heavy ion collisions, with normal hadrons not appearing until several fm/c after the start of the reaction. To test this hypothesis, correlations between charges and their associated anticharges are evaluated with the use of balance functions. It is shown that late-stage hadronization is characterized by tightly correlated charge/anticharge pairs when measured as a function of relative rapidity.
