标题： Higher order dynamical charge fluctuations in heavy-ion collisions

摘要： 逐次事件电荷涨落测量被提议用来提供重离子碰撞中夸克-胶子等离子体（QGP）的信号。动力学电荷涨落的测量预计会携带QGP相最终状态时的初始分数电荷信息。我们提出高阶电荷涨落测量来研究重离子碰撞中的QGP信号。这种高阶电荷涨落可观测量可以放大QGP的信号特征。此外，SMASH模型被用于研究这些可观测量在重离子碰撞中的行为，这些碰撞的能量是在STAR束流能量扫描计划中可达到的中心-of-质量能量。 显示英文摘要

摘要： The event-by-event charge fluctuation measurements are proposed to provide the signature of quark-gluon plasma (QGP) in heavy-ion collisions. Measure of dynamical charge fluctuations is expected to carry information of initial fractional charge of the QGP phase at the final state. We propose the higher order charge fluctuation measurement to study the QGP signal in heavy-ion collisions. This higher order charge fluctuation observable can amplify the signature of QGP. Also, the SMASH model is used to study the behavior of these observable in heavy-ion collisions at center of mass energies accessible in the STAR beam energy scan program.
