Heavy meson couplings in Hard-Wall AdS/QCD correspondence with Nf = 5

Abstract

In this article, Hard-Wall AdS/QCD with 5 flavors is used to study pseudoscalar, vector and axial-vector B meson. The mass and decay constants of B0, Bs0, Bc−, ηb, Bs⁎0, Bc⁎−, B1−, B1s0, B1c−, ηb and χb1 as well as strong couplings of (B¯⁎0,B⁎+,π−) (B⁎+,Bs⁎0,K+), (B¯10,B⁎+,π−), (B1⁎+,Bs⁎0,K+), (B¯10,B1+,ρ−), (B¯1+,Bs10,K⁎+), (B¯10,B⁎+,a0−), (B¯1+,Bs⁎0,K0+), (D¯⁎0,D⁎−,π−), (D¯⁎0,Ds⁎−,K+) (D¯⁎0,D1−,π−), (D¯⁎0,Ds1−,K+), (D¯10,D1−,ρ−), (D¯10,Ds1−,K⁎+), (D¯⁎0,D1−,a0−) and (D¯⁎0,Ds1−,K0+) 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.
