Abstract

We study the nonresonant three-body decays of B⁺→ D^(*)-_s K⁺ π⁺ and B_d→ D_s^(*)- K⁰ 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→ 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→ D_s^- K⁺.
