Abstract

We report the first observation of two Cabibbo-suppressed decay modes of the B<sub>s</sub><sup>0</sup> meson. Using a sample of pp̅ collisions at √s=1.96  TeV corresponding to 5.9  fb<sup>-1</sup> of integrated luminosity collected with the CDF II, the collider detector at the Fermilab Tevatron, we search for new B<sub>s</sub><sup>0</sup> decay modes in a sample of events containing J/ψ→μ<sup>+</sup>μ<sup>-</sup> decays. We reconstruct a B<sub>s</sub>0→J/ψK<sup>*</sup>(892)<sup>0</sup> signal with K<sup>*</sup>(892)<sup>0</sup>→K<sup>+</sup>π<sup>-</sup>, observing a yield of 151±25 events with a statistical significance of 8.0σ. We also reconstruct a B<sub>s</sub><sup>0</sup>→J/ψKS<sup>0</sup> signal with KS<sup>0</sup>→π<sup>+</sup>π<sup>-</sup>, observing a yield of 64±14 events with a statistical significance of 7.2σ. From these yields, we extract the branching ratios B(B<sub>s</sub><sup>0</sup>→J/ψK<sup>*</sup>(892)0)=(8.3±3.8)×10-5 and B(B<sub>s</sub><sup>0</sup>→J/ψK<sup>0</sup>)=(3.5±0.8)×10-5, where statistical, systematic, and fragmentation-fraction uncertainties are included in the combined uncertainty.
