Abstract

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nc QCD对神经网络相互作用的影响

我们提出了一种基于两核子相互作用的排序方法，该方法基于它们与QCD颜色的数量N c的比例，在N c变大的极限下。双核扇区的现有数据表明，这种排序大体上是一致的，这表明该方法在数据不太容易获得的其他情况下可能是有用的。然而，一些警告和潜在的陷阱可能使大N - c排序脆弱和/或容易被误解。我们讨论了大N - c分析在两核子和三核子相互作用中的应用，包括那些源自弱相互作用和BSM(超出标准模型)相互作用的相互作用，以及两核子外部电流。最后，讨论了该领域的一些开放性问题。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
