| Popis: | In this work we evaluate the coupling constant and the form factor for the vertex Bs*BK using the QCD Sum Rules. In this case we consider the B meson off shell. The only theoretical evaluation for the coupling constant was made using the Heavy Hadron Chiral Perturbation Theory (HHChPT) and we made comparison with this result. |
