Abstract

We present branching fraction measurements for the decays $B^{0} \to ρ^{0} K^{* 0}$ , $B^{0} \to f_{0} K^{* 0}$ , and $B^{0} \to ρ^{-} K^{* +}$ , where $K^{*}$ is an $S$ -wave $(K π)_{0}^{*}$ or a $K^{*} (892)$ meson; we also measure $B^{0} \to f_{0} K_{2}^{*} (1430)^{0}$ . For the $K^{*} (892)$ channels, we report measurements of longitudinal polarization fractions (for $ρ$ final states) and direct $C P$ violation asymmetries. These results are obtained from a sample of $(471.0 \pm 2.8) \times 10^{6}$ $B \bar{B}$ pairs collected with the BABAR detector at the PEP-II asymmetric-energy $e^{+} e^{-}$ collider at the SLAC National Accelerator Laboratory. We observe $ρ^{0} K^{*} (892)^{0}$ , $ρ^{0} (K π)_{0}^{* 0}$ , $f_{0} K^{*} (892)^{0}$ , and $ρ^{-} K^{*} (892)^{+}$ with greater than $5 σ$ significance, including systematics. We report first evidence for $f_{0} (K π)_{0}^{* 0}$ and $f_{0} K_{2}^{*} (1430)^{0}$ , and place an upper limit on $ρ^{-} (K π)_{0}^{* +}$ . Our results in the $K^{*} (892)$ channels are consistent with no direct $C P$ violation.
