Measurement of the time-integrated $C P$ asymmetry in $D^{0} \to π^{0} π^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, Y. Ahn +372

We measure the time-integrated $C P$ asymmetry, $A_{C P}$ , in $D^{0} \to π^{0} π^{0}$ decays reconstructed in $e^{+} e^{-} \to c c ˉ$ events collected by Belle II during 2019--2022. The data cor…

Observation of the decay $B^{0} \to J / ψ ω$ at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +383

We measure the branching fraction of the decay $B^{0} \to J / ψ ω$ using data collected with the Belle II detector at the SuperKEKB collider. The data contain $(387 \pm 6) \times 1 0^{6}$ …
