Search for lepton-flavor-violating $I ¨ ^{-} \to I^¼^{-} I^¼^{+} I^¼^{-}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +429

We present the result of a search for the charged-lepton-flavor violating decay $I ¨ ^{-} \to I^¼^{-} I^¼^{+} I^¼^{-}$ using a $424 f b^{- 1}$ sample of data recorded by the Belle II experiment at t…

Search for the decay $B^{0} \to I^^{3} I^^{3}$ using Belle and Belle II data

Belle, Belle II Collaborations, : +407

We report the result of a search for the rare decay $B^{0} \to I^^{3} I^^{3}$ using a combined dataset of $753 \times 1 0^{6}$ $B B ˉ$ pairs collected by the Belle experiment and $387\times…

New graph-neural-network flavor tagger for Belle II and measurement of $sin 2 I ¨ _{1}$ in $B^{0} \to J / I ¨ K_{S}^{0}$ decays

Belle II Collaboration, I. Adachi, L. Aggarwal +413

We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral $B$ mesons produced in $I^¥ (4 S)$ decays. It improves previous algorithms by usi…
