在AdS/QCD框架下，采用自底向上的方法对标量胶球和标量介子谱进行了唯象分析。所得的光谱与格点QCD结果胶球和介子PDG数据吻合得很好。利用AdS/QCD中模函数与光阵面QCD中波函数的关系讨论胶球与介子的混合。我们的研究结果指出，超过2 GeV的标量粒子将出现在几乎简并的非混合胶球和介子态对导致一个有趣的现象，从而胶子动力学可以很好地研究。
A phenomenological analysis of the scalar glueball and scalar meson spectra is carried out by using the AdS/QCD framework in the bottom-up approach. The resulting spectra are in good agreement for glueballs with lattice QCD results and for mesons with PDG data. We make use of the relation between the mode functions in AdS/QCD and the wave functions in Light-Front $QCD$ to discuss the mixing of glueballs and mesons. The results of our investigation point out that above 2 GeV scalar particles will appear in almost degenerate pairs of unmixed glueball and mesons states leading to an interesting phenomenology whereby gluon dynamics could be well investigated.
