相变时火球碎裂的特征

Signatures of fireball fragmentation at the phase transition

Boris Tomasik

摘要:

解释了在超相对论核碰撞中产生的火球在经过相变时为什么会碎裂以及如何碎裂。它可以发生在一阶相变,但不排除即使在高碰撞能量,其中存在平滑的交叉。两个潜在的观测敏感的出现的碎片:事件的快度分布和质子相关的相对快度事件的变化进行审查。

英文摘要:

It is explained why and how the fireball created in ultrarelativistic nuclear collisions can fragment when passing the phase transition. It can happen at the first-order phase transition but is not excluded even at high collision energies where the smooth crossover is present. Two potential observables sensitive to the appearance of fragmentation are reviewed: event-by-event changes of rapidity distributions and proton correlation in relative rapidity.
