论文摘要
在这项工作中，我们首先将其校正定为具有通用风味数字的D4-D8模型中调味量规场的偶数配置。然后，当D8-Branes上的激体构型在该模型中代表了同样的Baryon，保持了校正，因此我们可以系统地研究Baryon，重型Baryon或重型梅森的光谱，并发现可以在该模型中使用Meson数据拟合实验数据。此外，我们简要概述了如何在校正中包括粘合球和重型介子或巴里昂的相互作用，从数值上评估涉及粘合球的重灯膜或重重膜的衰减率。由于可以将参数相同选择的所有光谱拟合到实验数据中，因此我们认为我们的校正改进了D4-D8模型的框架，并且校正后的Instanton构型也可用于研究全息流中Baryon的其他特性。
In this work, we first derive the corrections to the instanton configuration of the flavored gauge field in the D4-D8 model with generic flavor numbers. Then, as the instanton configuration on the D8-branes represents equivalently baryon in this model, keeping our corrections in hand, we systemically study the spectrum of baryon, heavy-light baryon or heavy-light meson and find it is possible to fit the experimental data with the meson data in this model. Besides, we briefly outline how to include the interaction of glueball and heavy-light meson or baryon with our corrections, evaluate numerically the decay rate of the heavy-light meson or baryonic matter involving glueball. Since it is possible to fit all the spectra with same choice of the parameters to the experimental data, we believe our corrections improve the framework of D4-D8 model and the corrected instanton configuration is also useful to investigate other properties of baryon in holography.
