Analysis of $D_{s}D{K}^{\ast }$ and $D_s{D}^{\ast }{K}^{\ast }$ vertices and branching ratio of $B^{+}\to {K^{\ast }}^0{\pi }^{+}$

M. Janbazi, R. Khosravi

In this paper, the strong form factors and coupling constants of $D_{s}D{K}^{\ast }$ and $D_s{D}^{\ast }{K}^{\ast }$ vertices are investigated within the three-point QCD sum rules method with and without th…
