摘要
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..0,.. 0..,.. ..,....,..*0..,..*-..,..- 1,.. 01..,..- 1..,.... and....1 as well as strong couplings of ( <overline>.. *0,..*+,..-) (..*+,..*0..,..+), ( <overline>.. 01,..*+,.. -), (..*+ 1,..*0..,.. +), ( <overline>.. 01,.. + 1,..-), ( <overline>.. + 1,..0..1,..*+), ( <overline>.. 01,..*+,.. 0), ( <overline>.. + 1,..*0..,.. + 0), ( <overline>.. *0,..*-,.. -), ( <overline>.. *0,..*-..,.. +) ( <overline>.. *0,..- 1,..-), ( <overline>.. *0,..-..1,.. +), ( <overline>.. 01,..- 1,..-), ( <overline>.. 01,..-..1,.. *+), ( <overline>.. *0,..- 1,.. 0) and ( <overline>.. *0,..-..1,.. + 0) 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.
