Abstract
We present measurements of -meson decays to the final states , , and , where stands for a vector, scalar, or tensor strange meson. We observe a significant signal or evidence for and all the channels. We also measure, where applicable, the charge asymmetries, finding results consistent with no direct violation in all cases. The measurements are performed on a data sample consisting of pairs, collected with the BABAR detector at the PEP-II 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 with respect to the vector component.
