Abstract
We use the decay modes B→K* 0(1430)π and B→a0(980)K to study the scalar mesons K* 0(1430) and a0(980) within the framework of perturbative QCD. For B→K* 0(1430)π, we perform our calculation in two scenarios for the scalar meson spectrum. The results indicate that scenario II is more favored by the experimental data than scenario I. The important contribution from annihilation diagrams can enhance the branching ratios by about 50% in scenario I and about 30% in scenario II. The direct CP-asymmetries in B→K* 0(1430)π are small, which is consistent with the present experiments. The predicted branching ratio of B→a0(980)K in scenario I differs from the experiments by a factor of 2, which indicates that a0(980) cannot be interpreted as q̄q.
