- Abstract
Inspired by the brilliant prospects of the ongoing B meson experiments, the hadronic charmless B → SS decays are studied by considering the next-to-leading (NLO) contributions with the QCD factorization approach, where S denotes the scalar mesons K 0 ∗ (1430) and a 0 (1450) . Branching ratios and CP violating asymmetries are estimated with the updated values of hadronic parameters obtained from a covariant light-front quark model, for two scenarios where the scalar mesons are the 1 3 P 0 and 2 3 P 0 states. It is found that the NLO contributions are very important for the B → SS decays. For the B → a 0 (1450) K 0 ∗ (1430) and B s → K 0 ∗ (1430) K ¯ 0 ∗ (1430) decays, branching ratios can reach up to the order of O (10 - 5) by assuming that the scalar mesons are the 1P states, and should first be investigated in the future experiments.
