Abstract:
We study the nonresonant three-body decays of B+→D(*)−sK+π+ and Bd→Ds(*)−K0π+. We find that these decays can provide the information on the time-like form factors of D(*)sK. We also explicitly investigate Bd→Ds(*)−K*+ decays by discriminating the nonresonant contributions with the unknown D(*)s wave functions being fixed by the measured mode of Bd→Ds−K+.
