论文摘要
这项工作探讨了一项全息建议，可以通过考虑对众所周知的自下而上的广告/QCD建议，硬盘和软墙模型来描述光核素光谱。我们还提出了一个受伍兹 - 撒克逊潜力启发的替代描述。我们发现在这种类似木 - 撒克逊模型中的潜力相关的静态DILATON。我们计算了核素光谱发现，尽管它们的纯广告/QCD起源，但Hardwall和Softwall作为单极管模型，但由于RMS误差分别接近11 $ \％$ \％$和4 $ \％$，因此具有良好的精度和精度。对于木制型号，RMS约为1 $ \％$。我们还讨论了配置熵，作为对哪种模型进行分类的工具，适合描述稳定性的核素。我们发现，在考虑软墙和木 - 撒克逊模型时，构型熵类似于与核自旋无关的稳定线。对于硬墙情况，尽管成分数量增加，但构型熵取决于核自旋。因此，木材撒克逊人样模型是描述自下而上场景中光核素光谱法的最佳选择。
This work explores a holographic proposal to describe light nuclide spectroscopy by considering extensions to the well-known bottom-up AdS/QCD proposals, the hardwall and softwall models. We also propose an alternative description inspired by the Woods-Saxon potential. We find the static dilaton associated with this potential in this Wood-Saxon-like model. We compute the nuclide spectra finding that, despite their pure AdS/QCD origin, hardwall and softwall, as monoparametric models, have good accuracy and precision since the RMS error is near 11 $\%$ and 4 $\%$ respectively. In the case of the Wood-Saxon model, the RMS was around 1 $\%$. We also discuss configurational entropy as a tool to categorize which model is suitable to describe nuclides in terms of stability. We found that configurational entropy resembles a stability line, independent from nuclear spin, for symmetric light nuclides when considering softwall and Wood-Saxon-like models. For the hardwall case, configurational entropy, despite increasing with the constituent number, depends on the nuclear spin. Thus, the Woods-Saxon-like model emerges as the best choice to describe light nuclide spectroscopy in the bottom-up scenario.
