dc.descriptionThe BaBar collaboration has recently reported the observation of the decay mode $B^-\to D_s^+ K^- π^-$. We investigate the role played by the $D^{\star\star}$ resonances in this decay mode using HQET. Although these resonances cannot appear as physical intermediate states in this reaction, their mass is very close to the $D_s^+ K^-$ production threshold and may, therefore, play a prominent role. We pursue this possibility to extract information on the properties of the strong $D^{\star\star} D M$ couplings. As a byproduct of this analysis we point out that future super-$B$ factories may be able to measure the $D_0^0 D^\star γ$ radiative coupling through the reaction $B^-\to D^\star γπ^-$.
