论文摘要
我们试图通过将较高的尺寸组件（作为重的介体）引入Sakai-Sugimoto模型。使用遗体和曼顿方法，我们获得了一个由重的介子和光口味偶尔组成的理论。应用集体坐标量化方法，我们得出了重型重子的质量公式。以$ 1/m_ {h} $膨胀的领先顺序（$ m_ {h} $ the the heavy Quark的质量），我们在重的夸克对称性（HQS）中找到了Singlet和Doublet状态。同样，我们获得了堕落的绳索和奇特的平价激发。凭借沉重的介子自由度，我们的质量公式重现了$σ^*_ c $和$λ_c^*$的质量顺序。
We try to introduce heavy flavors to Sakai-Sugimoto model by regarding higher dimensional components of gauge fields as heavy mesons. Using the Forgács and Manton approach, we obtain a theory composed of heavy mesons and the instanton of light flavors. Applying the collective coordinate quantization method, we derived a mass formula of heavy baryons. In the leading order of $1/m_{H}$ expansion ($m_{H}$ the mass of a heavy quark), we find singlet and doublet states in the heavy quark symmetry (HQS). Also, we obtain the degenerate Roper like and odd parity excitations. By virtue of heavy meson degrees of freedom, our mass formula reproduces the mass ordering of $Σ^*_c$ and $Λ_c^*$ correctly.
