论文摘要
通过在冷却过程中的绝热假设，我们讨论了upsilon（1s）抑制的新机制，这是由于火球早期的快速加热过程，而不是其在重离子碰撞中产生的有限温度介质中的有限衰变宽度。我们计算了快速加热解离后的过渡概率，这是中央碰撞中培养基温度和核修饰因子的函数，并发现RHIC的抑制也不可忽略不计，即使UPSILON（1s）的宽度消失了。
With the adiabatic assumption in the cooling process, we discussed a new mechanism on Upsilon(1S) suppression that is due to the fast heating process at the early stage of the fireball instead of its finite decay width in finite temperature medium produced in the heavy ion collisions. We calculated the transition probability after the fast heating dissociation as a function of the temperature of the medium and the nuclear modification factor in central collisions, and found that the suppression is not negligible at RHIC, even if the width of Upsilon(1S) vanishes.
