论文摘要
需要调和我们对广泛的密度范围内对腺体物质行为的理解，尤其是在来自多中途观察和新颖的实验设施的数据泛滥的时候，已经为核模型提供了新的挑战。特别是，如果需要在相同的基础上进行PREX-II（或PREX）和CREX等实验，则核能功能的ISOVECTOR通道的密度依赖性似乎很难固定。我们通过对中子星的静态特性进行完整的贝叶斯分析，以及在半经典水平上计算出的中子能量，电荷半径和中性皮肤，通过对中子星的静态特性进行完整的贝叶斯分析来测试这种异常。我们的结果表明，散装和表面特性之间的相互作用以及有效地解除订购和过饱和密度状态的高阶经验参数的重要性可能部分解释了不同的测量和观察结果之间的张力。但是，如果表面行为与散装特性脱钩，我们发现实验和观察性数据中存在一个和谐的情况。
The need of reconciling our understanding of the behavior of hadronic matter across a wide range of densities, especially at the time when data from multimessenger observations and novel experimental facilities are flooding in, has provided new challenges to the nuclear models. Particularly, the density dependence of the isovector channel of the nuclear energy functionals seems hard to pin down if experiments like PREX-II (or PREX) and CREX are required to be taken on the same footing. We put to test this anomaly in a semi-agnostic modelling technique, by performing a full Bayesian analysis of static properties of neutron stars, together with global properties of nuclei as binding energy, charge radii and neutron skin calculated at the semi-classical level. Our results show that the interplay between bulk and surface properties, and the importance of high order empirical parameters that effectively decouple the subsaturation and the supersaturation density regime, might partially explain the tension between the different measurements and observations. If the surface behaviors, however, are decoupled from the bulk properties, we found a rather harmonious situation among experimental and observational data.
