$B_s{B}^{\ast }K$ and $B_{s}B{K}^{\ast }$ vertices using QCD sum rules

A. Cerqueira, B. Osório Rodrigues, M. E. Bracco +1

The form factors and the coupling constant of the $B_s{B}^{\ast }K$ and $B_{s}B{K}^{\ast }$ vertices are calculated using the QCD sum rules method. Three point correlation functions are compute…
