B-meson decays to η′ρ , η′f0 , and η′K*

Abstract

We present measurements of B -meson decays to the final states η ′ ρ , η ′ f 0 , and η ′ K ∗ , where K ∗ stands for a vector, scalar, or tensor strange meson. We observe a significant signal or evidence for η ′ ρ + and all the η ′ K ∗ channels. We also measure, where applicable, the charge asymmetries, finding results consistent with no direct C P violation in all cases. The measurements are performed on a data sample consisting of 467 × 10 6 B ¯¯¯ B pairs, collected with the BABAR detector at the PEP-II e + e − collider at the SLAC National Accelerator Laboratory. Our results favor the theoretical predictions from perturbative QCD and QCD factorization and we observe an enhancement of the tensor K ∗ 2 ( 1430 ) with respect to the vector K ∗ ( 892 ) component.
