标题： Bulk medium properties of heavy-ion collisions from the beam energy scan with a multistage hydrodynamic model

摘要： 我们介绍一种方法，用于重建带电粒子多重性和净质子产率的完整快速度分布，这对于限制在束流能量扫描计划中产生的核物质的纵向动力学至关重要。 在针对Au+Au碰撞在$\sqrt{s_\mathrm{NN}}=7.7-200\,$GeV 校准的多阶段流体力学模型中，我们利用快速度分布，估计了沉积到碰撞火球中的总能量和重子数，为初始动力学提供了见解，并识别了核残留物。 我们探讨了依赖快速度的测量在探测有限化学势下的状态方程的潜力。 此外，我们将从流体力学和热模型中得出的冻结参数进行比较，强调通过热模型提取的参数代表了 across 快速度的平均特性。 显示英文摘要

摘要： We introduce a method to reconstruct full rapidity distributions of charged particle multiplicity and net proton yields, crucial for constraining the longitudinal dynamics of nuclear matter created in the beam energy scan program. Employing rapidity distributions within a multistage hydrodynamic model calibrated for Au+Au collisions at $\sqrt{s_\mathrm{NN}}=7.7-200\,$GeV, we estimate the total energy and baryon number deposited into the collision fireball, offering insights into initial dynamics and the identification of nuclear remnants. We explore the potential of rapidity-dependent measurements in probing equations of state at finite chemical potentials. Furthermore, we compare the freeze-out parameters derived from both hydrodynamics and thermal models, highlighting that the parameters extracted via thermal models represent averaged properties across rapidities.
