论文摘要
我简要回顾了状态核方程（EOS）和能量密度功能（EDF）的儿童理论框架，我讨论了对称能量的曲率参数的最新结果，并讨论了Prex-Crex拼图。我表明，可以获得可以在其各自的误差栏内复制prex-II和Crex结果的EDF模型。这样的EDF对应于EOSS，它向低密度软化，这可能归因于聚类。在这种情况被认为是可行的之前，还应检查偶极子极化性。
I briefly review the KIDS theoretical framework for the nuclear equation of state (EoS) and energy density functional (EDF), I discuss recent results for the curvature parameter of the symmetry energy, and I address the PREX-CREX puzzle. I show that it is possible to obtain EDF models which can reproduce both PREX-II and CREX results each within its respective error bars. Such EDFs correspond to EoSs which soften towards low densities, as could be attributed to clusterization. Before such a scenario is considered viable, the dipole polarizability should also be examined.
