We present a method for ordering two-nucleon interactions based upon their scaling with the number of QCD colors, N c, in the limit that N c becomes large. Available data in the two-nucleon sector show general agreement with this ordering, indicating that the method may be useful in other contexts where data are less readily available. However, several caveats and potential pitfalls can make the large- N c ordering fragile and/or vulnerable to misinterpretation. We discuss the application of the large- N c analysis to two- and three-nucleon interactions, including those originating from weak and BSM (beyond the Standard Model) interactions, as well as two-nucleon external currents. Finally, we discuss some open questions in the field.

大型数控 QCD 对神经网络相互作用的影响


我们提出了一种根据 QCD 颜色数量 N 的缩放来对两个核子相互作用进行排序的方法c ，在 N 的限制下c变大。双核子区域中的可用数据显示与此排序基本一致，表明该方法可能在数据不易获得的其他情况下有用。然而，一些警告和潜在的陷阱可能会使大N c订购脆弱和/或容易被误解的产品。我们讨论大N的应用c对二核子和三核子相互作用的分析，包括源自弱相互作用和 BSM（超出标准模型）相互作用的分析，以及二核子外电流。最后，我们讨论该领域的一些悬而未决的问题。
