Study of Decay Modes B -->K_0^*(1430) phi

Understand

Within the framework of perturbative QCD approach based on $\mathbf{k_T}$ factorization, we investigate the charmless decay mode $B \to K_0^*(1430)\phi$.

• Under two different scenarios (S1 and S2) for the description of scalar meson $K_0^*(1430)$, we explore the branching fractions and related CP asymmetries.
• Besides the dominant contributions from the factorizable emission diagrams, penguin operators in the annihilation diagrams could also provide considerable contributions.
• The central values of our predictions are larger than those from the QCD factorization in both scenarios.
