Abstract
In this proceeding, we made an critical comparison between our method used in the calculation of
form factor and coupling constant using the QCD Sum rules method and other one method using
also QCDSR (Eur.Phys.J.C 78 (2018) 7, 606).
The vertex that we are comparing is the $D_s DK^*$, that is important to compute cross section of the
process $B \to K^* \pi$ within effective theories.
