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…

Search for $C P$ violation using $T$ -odd correlations in $D_{(s)}^{+} \to K^{+} K^{-} π^{+} π^{0}$ , $D_{(s)}^{+} \to K^{+} π^{-} π^{+} π^{0}$ , and $D^{+} \to K^{-} π^{+} π^{+} π^{0}$ decays

Belle Collaboration, L. K. Li, A. J. Schwartz +174

We search for $C P$ violation using $T$ -odd correlations in five $D_{(s)}^{+}$ and $D_{(s)}^{-}$ four-body decays. Our analysis is based on 980 $f b^{- 1}$ of data collected by…
