论文摘要
我们研究了在$ 1 \ a {\ rm gev} \ le e e _ {\ rm lab} \ le 10 \ a {\ rm gev} $的公平/nica能量范围内重离子反应的辐射颗粒光谱和流动特性。通过在恒定能量密度的超出表面上抽样大型强子气体的Cooper-Frye分布来实现颗粒化。给出了不同状态基础方程的流体动力计算结果，并将其与实验数据和微观传输模拟进行了比较。研究了对物理模型的方法输入有关初始状态和参与化的敏感性。
We investigate hadronic particle spectra and flow characteristics of heavy-ion reactions in the FAIR/NICA energy range of $1\ A{\rm GeV} \le E_{\rm lab} \le 10\ A{\rm GeV}$ within a relativistic ideal hydrodynamic one-fluid approach. The particlization is realized by sampling the Cooper-Frye distribution for a grand canonical hadron gas on a hypersurface of constant energy density. Results of the hydrodynamic calculations for different underlying equations of state are presented and compared with experimental data and microscopic transport simulations. The sensitivity of the approach to physical model inputs concerning the initial state and the particlization is studied.
