论文摘要
通过根据我们在ANN中开发的结果恢复一系列梯子图来研究无限的核物质。物理。 437，168741（2022）。在对核子核子相互作用的无挑战描述中，对于接触相互作用的情况，明确解决了能量密度的主公式。获得了重新归一化的结果，这些结果是根据核子核子相迁移直接表达的，并以部分波幅度的幅度混合角度，直至包括$ g $波，并在较高的部分波的包含下达到收敛。梯度系列产生的每个粒子的能量，密度和声速用于对称和中子物质。梯形图的这种重新介绍提供了严格的结果，可以用作$ \ bar {\ cal {e}} $的其他参数化的低密度参考，以实现更高的密度。
Infinite nuclear matter is studied by resuming the series of ladder diagrams based on the results developed by us in Ann. Phys. 437, 168741 (2022). The master formula for the energy density is explicitly solved for the case of contact interactions, within a pionless description of the nucleon-nucleon interactions. Renormalized results are obtained which are directly expressed in terms of the nucleon-nucleon phase shifts and mixing angles in partial-wave amplitudes up to an including $G$ waves, with convergence reached under the inclusion of higher partial waves. The energy per particle, density and sound velocity resulting from the ladder series are given for symmetric and neutron matter. This resummation of the ladder diagrams provides a rigorous result that may be used as low-density reference for other parameterizations of $\bar{\cal{E}}$ for higher densities.
