Properties of nuclear matter are investigated in the framework of relativistic Brueckner–Hartree–Fock model with the latest high-precision charge-dependent Bonn (pvCD-Bonn) potentials, where the coupling between pion and nucleon is adopted as a pseudovector form. These realistic pvCD-Bonn potentials are renormalized to effective nucleon–nucleon (NN) interactions, G matrices. They are obtained by solving the Blankenbecler-Sugar (BbS) equation in nuclear medium. Then, the saturation properties of symmetric nuclear matter are calculated with pvCD-Bonn A, B, C potentials. The energies per nucleon are around −10.72 MeV to −16.83 MeV at saturation densities, 0.139 fm −3 to 0.192 fm −3 with these three potentials, respectively. It clearly demonstrates that the pseudovector coupling between pion and nucleon can generate reasonable saturation properties comparing with pseudoscalar coupling. Furthermore, these saturation properties have strong correlations with ...

具有高精度电荷依赖势的相对论性Brueckner–Hartree–Fock模型中核物质的性质

在具有最新高精度电荷依赖波恩（pvCD-Bonn）势的相对论性Brueckner-Hartree-Fock模型的框架内研究核物质的性质，其中pion和核子之间的耦合被用作伪向量形式。将这些现实的pvCD-Bonn势重新归一化为有效的核子-核子（NN）相互作用G矩阵。它们是通过在核介质中求解布兰肯贝克勒-糖（BbS）方程获得的。然后，利用pvCD-Bonn A，B，C势计算对称核物质的饱和特性。在饱和密度下，每个核子的能量约为-10.72 MeV至-16.83 MeV，在这三个电势下分别为0.139 fm -3至0.192 fm -3。它清楚地表明，与伪标量耦合相比，pion和核子之间的伪矢量耦合可以生成合理的饱和特性。此外，这些饱和度特性与...
