论文摘要
核问题的封闭形式的brükner$ g $矩阵计算在$^1S_0 $的eft（$ \ not \！\！π$）的$^1S_0 $通道中，并在非驱动性上下文中重新归一化。核中型环境产生的其他约束与脱壳$ t $矩阵的重归于一致，使功率计数完整并简化EFT耦合的运行行为。通过获得$ g $，我们为中子和对称核物质计算了每个粒子的能量，以证明由非扰动重新归一化引起的某些“物理”参数的物理相关性。我们还通过检查给定密度的封闭形式$ g $矩阵的极点，在$^1S_0 $通道中探索了配对现象，在此再次清楚地说明了同一集物理参数的物理相关性。
The closed-form Brükner $G$ matrix for nuclear matter is computed in the $^1S_0$ channel of EFT($\not\!\!π$) 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 $^1S_0$ 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.
