Contributions of K0∗1430 and K0∗1950 in the Charmed Three-Body B Meson Decays

Abstract

In this work, we investigate the resonant contributions of K0∗1430 and K0∗1950 in the three-body Bs⟶DsKπ within the perturbative QCD approach. The form factor Fkπs is adopted to describe the nonperturbative dynamics of the S-wave Kπ system. The branching ratios of all concerned decays are calculated and predicted to be in the order of 10−10 to 10−5. The ratio R of branching fractions between B0⟶D¯0K0∗01430⟶D¯0K+π− and Bs0⟶D¯0K¯0∗01430⟶D¯0K−π+ is predicted to be 0.0552, which implies the discrepancy for the LHCb measurements. We expect that the predictions in this work can be tested by the future experiments, especially, to resolve R ratio discrepancy.
