论文摘要
我们提出了一种基于QCD颜色$ N_C $的缩放量表的订购方法,以$ n_c $变大的限制。两个努克莱恩部门中的可用数据显示了与此顺序的一般共识,表明该方法在数据较不容易获得的其他情况下可能很有用。但是,几个警告和潜在的陷阱可以使大$ n_c $订购脆弱和/或容易犯错的误解。我们讨论了大型$ N_C $分析在两种和三核互动中的应用,包括源自弱和超越标准模型相互作用的互动,以及两种核电的外部电流。最后,我们讨论了该领域的一些开放问题。
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 shows general agreement with this ordering, indicating that the method may be useful in other contexts where data is 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 beyond-the-standard-model interactions, as well as two-nucleon external currents. Finally, we discuss some open questions in the field.
