标题： Probing the softest region of nuclear equation of state

摘要： 一种吸引人的、与能量相关的平均场势能被引入，以在核状态方程中产生一个软区域，这由最近的有限温度下重子自由物质的格点QCD计算所建议。 基于一个强子输运模型，我们发现尽管这种状态方程对包含的强子谱几乎没有影响，但它会导致横向集体流的能量依赖性出现最小值，并导致压缩物质的膨胀延迟。 特别是，当碰撞系统通过状态方程中的最软区域时，横向流的方向会发生变化。 显示英文摘要

摘要： An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation-of-state, as suggested by recent lattice QCD calculations of baryon free matter at finite temperature. Based on a hadronic transport model, we find that although this equation-of-state has negligible effects on the inclusive hadronic spectra, it leads to a minimum in the energy dependence of the transverse collective flow and a delayed expansion of the compressed matter. In particular, the transverse flow changes its direction as the colliding system passes through the softest region in the equation-of-state.
