Abstract

In light of the recent experimental results on decays B⁺ → f_X(1300)K⁺ and B^±(0) → J/Ψ K_X^*±(0)(1430) from Belle, we study the B → P(V)S type decays, B^±(0) → f ₀(1370)K^±(0) and B^±(0) → J/Ψ K₀^*±(0)(1430), in comparison with the B → P(V)T type decays, B^±(0) → f ₂(1270)K^±(0) and B^±(0) → J/Ψ K₂^*±(0)(1430). We calculate the BRs for these decays by using the form factors obtained in the ISGW2 model (the improved version of the original Isgur-Scora-Grinstein-Wise (ISGW) model), as well as the ISGW model for comparison. The ratios of β(B → P(V)S)/β(B → P(V)T) are also presented.
