论文摘要
我们对中微子核子反平均自由路径（IMFP）与状态的基础方程（EOSS）之间的相关性进行了广泛的研究。中微子平均自由路径中的强相互作用不确定性在不同的密度方案中进行了研究。核子有效质量，核子化学电位和培养基中的残留相互作用在以密度依赖性方式确定中微子核子相互作用方面起着重要作用。我们研究上述数量如何受到与（i）核质量测量，（ii）质子 - 蛋白质散射相位移动和（iii）Neutron Star观测值一致的EOS的约束。然后，我们使用Hartree-Fock+随机相位近似方法研究了带电电流和中微中微子核子反平均路径的不确定性和中微中微子核子反平均路径的不确定性。最后，我们计算（i）基于EOS的数量和基于EOS的数量之间的Pearson相关系数； （ii）基于EOS的数量和IMFP； （iii）IMFP和IMFP。我们发现残留相互作用对旋转和自旋 - 异种通道中中微子不透明度的强烈影响，这些通道并未受到当前核模型的限制。
We perform an extensive study of the correlations between the neutrino-nucleon inverse mean free paths (IMFPs) and the underlying equation of states (EoSs). Strong interaction uncertainties in the neutrino mean free path are investigated in different density regimes. The nucleon effective mass, the nucleon chemical potentials, and the residual interactions in the medium play an important role in determining neutrino-nucleon interactions in a density-dependent manner. We study how the above quantities are constrained by an EoS consistent with (i) nuclear mass measurements, (ii) proton-proton scattering phase shifts, and (iii) neutron star observations. We then study the uncertainties of both the charged current and the neutral current neutrino-nucleon inverse mean free paths due to the variation of these quantities, using Hartree-Fock+random phase approximation method. Finally, we calculate the Pearson correlation coefficients between (i) the EoS-based quantities and the EoS-based quantities; (ii) the EoS-based quantities and the IMFPs; (iii) the IMFPs and the IMFPs. We find a strong impact of residual interactions on neutrino opacity in the spin and spin-isospin channels, which are not well constrained by current nuclear modelings.
