In light of the recent experimental results on decays B+ → fX(1300)K+ and B±(0) → J/Ψ KX*±(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.
