Abstract

We present a study of three B⁰ decay modes useful for time-dependent CP asymmetry measurements. From a sample of 9.7×10⁶ BB̄ meson pairs collected with the CLEO detector, we have reconstructed B⁰ →J/ψK_S⁰, B⁰→χ_clK_S⁰, and B⁰→J/ψπ⁰ decays. The latter two decay modes have been observed for the first time. We describe a K_S⁰→π⁰π⁰ detection technique and its application to the reconstruction of the decay B⁰ →J/ψK_S⁰. Combining the results obtained using K_S⁰→π⁺π^- and K_S⁰→π⁰π⁰ decays, we determine B(B⁰ →J/ψK⁰)=(9.5±0.8±0.6)×10^-4, where the first uncertainty is statistical and the second one is systematic. We also obtain B(B⁰→χ_clK⁰)=(3.9_-1.3 ^+1.9±0.4)×10^-4 and B(B⁰→J/ψπ⁰)=(2.5_-0.9 ^+1.1±0.2)×10^-5.
