论文摘要
我们报告了一项研究的结果，旨在推断令人反感的三个核子潜在的$ v^r_ {ijk} $ \ textemdash，从天体物理观测值中推动了核问题的刚度\ textemdash。使用贝叶斯方法，我们利用了较好的卫星和Ligo/pirgo协作进行的质量，半径和潮汐畸形的测量，以及最重的观察到的脉冲星的质量，以限制$ v^r_ {ijk} $的强度。我们的分析的基线是广泛使用的核哈密顿量，包括Argonne $ v_ {18} $ nucleon-nucleon潜力和三核电潜力的Urbana IX模型。数值结果在很大程度上取决于最大质量的界限，这表明现有的和未来的设施有可能在上近密度下对微观核动力学提供宝贵的新见解。
We report the results of a study aimed at inferring direct information on the repulsive three-nucleon potential $V^R_{ijk}$\textemdash driving the stiffness of the nuclear matter equation of state at supranuclear densities\textemdash from astrophysical observations. Using a Bayesian approach, we exploit the measurements of masses, radii and tidal deformabalities performed by the NICER satellite and the LIGO/Virgo collaboration, as well as the mass of the heaviest observed pulsar, to constrain the strength of $V^R_{ijk}$. The baseline of our analysis is the widely employed nuclear Hamiltonian comprising the Argonne $v_{18}$ nucleon-nucleon potential andthe Urbana IX model of three-nucleon potential. The numerical results, largely determined by the bound on the maximum mass, suggest that existing and future facilities have the potential to provide valuable new insight into microscopic nuclear dynamics at supranuclear densities.
