In this article, Hard-Wall AdS/QCD with 5 flavors is used to study pseudoscalar, vector and axial-vector meson. The mass and decay constants of , , , , , , , , , and as well as strong couplings of , , , , , , , , , , , , and vertices are estimated in this study. A comparison of the results of the masses, decay constants, and strong couplings with existing predictions is also made.
在本文中，具有5种味的硬壁反德西特/量子色动力学（Hard-Wall AdS/QCD）被用于研究赝标量、矢量和轴矢量介子。本研究估计了(\pi)、(K)、(\rho)、(K^*)、(a_1)、(K_1)、(f_0)、(f_1)、(f_2)、(a_2)和(\omega)的质量和衰变常数，以及(\pi\pi)、(KK)、(\pi\rho)、(K\rho)、(\rho\rho)、(K^K^)、(\pi a_1)、(K a_1)、(\rho a_1)、(K^*a_1)、(a_1a_1)、(K_1K_1)、(f_0f_0)、(f_1f_1)、(f_2f_2)和(\omega\omega)顶点的强耦合。还将质量、衰变常数和强耦合的结果与现有预测进行了比较。
