Abstract

We study the nonresonant three-body decays of $B^{+} \to D_{s}^{(*) -} K^{+} π^{+}$ and $B_{d} \to D_{s}^{(*) -} K^{0} π^{+}$ . We find that these decays can provide the information on the time-like form factors of $D_{s}^{(*)} K$ . We also explicitly investigate $B_{d} \to D_{s}^{(*) -} K^{*+}$ decays by discriminating the nonresonant contributions with the unknown $D_{s}^{(*)}$ wave functions being fixed by the measured mode of $B_{d} \to D_{s}^{-} K^{+}$ .
