Bayesian analyses on both isoscalar and isovector nuclear interaction parameters are carried out based on the Korea-IBS-Daegu-SKKU (KIDS) model under the constraints of nuclear structure data of $^{208}$Pb and $^{120}$Sn. Under the constraint of the neutron-skin thickness, it is found that incorporating the curvature parameter $K_{sym}$ of nuclear symmetry energy as an independent variable significantly broadens the posterior probability distribution function (PDF) of the slope parameter $L$, and affects the related correlations. Typically, the anticorrelation between $L$ and the symmetry energy at saturation density disappears, while a positive correlation between $L$ and $K_{sym}$ is observed. Under the constraint of the isoscalar giant monopole resonance (ISGMR), incorporating the skewness parameter as an independent variable also significantly broadens the posterior PDF of the nuclear matter incompressibility $K_0$. Even with the broad uncertainties of higher-order parameters of the equation of state (EOS), robust constraints of $L<90$ MeV and $K_0<270$ MeV are obtained. Our study quantifies the consistency between the constraints on $L$ from the neutron-skin data of PREXII and isovector giant dipole resonance (IVGDR) data, and the constraints on $K_0$ from the data of ISGMR in $^{208}$Pb and $^{120}$Sn.

Bayesian inference of nuclear symmetry energy from measured and imagined neutron skin thickness in $^{116,118,120,122,124,130,132}$Sn, $^{208}$Pb, and $^{48}$Ca
重核中的中子皮厚度$Δr_{np}$被认为是探测核物质饱和密度$ρ_0$的最灵敏的地面探测器之一。现有的中子皮数据大多来自强子观测,具有很大的不确定性,并且从实验中提取的数据往往强烈依赖于模型。在急切地等待来自宇称违反电子散射实验的、与模型无关的、高精度的$^{208}$ Pb和$^{48}$ Ca的中子皮数据的同时(JLab的PREX-II和CREX以及MESA的MREX),在使用Skyrme-Hartree-Fock模型的贝叶斯统计框架内,我们推断后验概率分布函数(PDF)从想象的$Δr_{np}(^{208}$ Pb $)=0.15$,0.20和0.30 fm以及$Δr_{np}(^{48}$ Ca $)=0.12$,0.15和0.25 fm,以及不同的$1σ$误差条,计算$ρ_0$处核对称能的斜率参数$L$。的$L$推断使用相同的方法从现有的$Δr_{np}$数据的Sn同位素强子探针的PDF的结果进行了比较。它们还比较了最近的贝叶斯分析的结果的半径和潮汐变形数据的正则中子星从GW 170817和NICER。Sn同位素的中子皮数据分别给出了围绕其平均值的$L=45.5^{+26.5}_{-21.6}$ MeV或围绕其最大值的$L=53.4^{+18.6}_{-29.5}$ MeV { \it a posteriori},后者小于但与中子星数据的$L=66_{-20}^{+12…
