The closed-form Brückner G matrix for nuclear matter is computed in the ${}^{1}S_0$ channel of EFT(π̸) and renormalized in nonperturbative context. The nuclear medium environment yields additional constraints that are consistent with off-shell T matrix renormalization, keeping the power counting intact and simplifying the running behaviors of the EFT couplings. With the G obtained we computed the energy per particle for neutron and symmetric nuclear matter to demonstrate the physical relevance of certain ‘physical’ parameters that arise from nonperturbative renormalization. We also explored the pairing phenomenon in ${}^{1}S_0$ channel by examining the poles of the closed-form G matrix with a given density, where again the physical relevance of the same set of physical parameters are clearly illustrated.

闭合形式布鲁克纳ģ为核物质矩阵计算在${}^{\mathrm{1个}}\mathrm{小号}_0$EFT（π̸）通道并在非扰动上下文中重新规范化。核介质环境产生了与壳外T矩阵重新规范化相一致的其他约束，从而保持了功率计数的完整性并简化了EFT耦合器的运行行为。利用获得的G，我们计算出中子和对称核物质的每个粒子的能量，以证明某些由非扰动重新归一化产生的“物理”参数的物理相关性。我们还探讨了${}^{\mathrm{1个}}\mathrm{小号}_0$通过检查具有给定密度的闭合形式G矩阵的极点来确定通道，再次清楚地说明了同一组物理参数的物理相关性。
