Abstract

In this letter we introduce an integral equation that allows to calculate the exact left-hand-cut discontinuity for an uncoupledS-wave partial-wave amplitude in potential scattering for a given finite-range potential. In particular this is applied here to theS01nucleon–nucleon (NN) partial wave. The calculation ofΔ(A)is completely fixed by the potential because short-range physics (corresponding to integrated out degrees of freedom within the low-energy Effective Field Theory) does not contribute toΔ(A). The results obtained from theN/Dmethod for a partial-wave amplitude are rigorous, since now the discontinuities along the left-hand cut and right-hand cut are exactly known. This solves in this case the op

在这封信中我们介绍一个整体方程，允许计算未耦合 - 在给定有限范围电位的潜在散射中的局部波振幅。特别是这在此处应用于 S 0 1 Nucleon-Nucleon（ NN ）部分波。计算 Δ （ a ）完全由潜力固定，因为短程物理（对应于低能量有效场理论内的集成自由度）没有贡献 Δ （ a ）。从 n / d 部分用于部分 - 波幅幅度严谨，因为现在沿左手切割和右侧切割的不连续性恰恰是已知的。这种情况解决了OP
