Measurement of the branching fractions of $B ˉ \to D^{()} K^{-} K_{(S)}^{() 0}$ and $B ˉ \to D^{(*)} D_{s}^{-}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +404

We present measurements of the branching fractions of eight $B^{0} \to D^{(*) +} K^{-} K_{(S)}^{(*) 0}$ , $B^{-} \to D^{(*) 0} K^{-} K_{(S)}^{(*) 0}$ decay channels. The results are…

Measurements of the branching fractions of $Ξ_{c}^{0} \to Ξ^{0} π^{0}$ , $Ξ_{c}^{0} \to Ξ^{0} η$ , and $Ξ_{c}^{0} \to Ξ^{0} η^{'}$ and asymmetry parameter of $Ξ_{c}^{0} \to Ξ^{0} π^{0}$

Belle, Belle II Collaborations, : +382

We present a study of $Ξ_{c}^{0} \to Ξ^{0} π^{0}$ , $Ξ_{c}^{0} \to Ξ^{0} η$ , and $Ξ_{c}^{0} \to Ξ^{0} η^{'}$ decays using the Belle and Belle~II data samples, which have integrated lumi…

Search for the decay $B^{0} \to γ γ$ using Belle and Belle II data

Belle, Belle II Collaborations, : +407

We report the result of a search for the rare decay $B^{0} \to γ γ$ using a combined dataset of $753 \times 1 0^{6}$ $B B ˉ$ pairs collected by the Belle experiment and $387\times10…
