Study of the nonleptonic charmless B → SS decays with the QCD factorization approach

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(& lowast;) (1430) and a(0)(1450). Branching ratios and C P 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 13P(0) and 23 P0 states. It is found that the NLO contributions are very important for the B -> SSdecays. For the B -> a(0)(1450)K-0(& lowast;) (1430) and Bs -> K-0(& lowast;) (1430)K-0(& lowast;)(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.
