Test of light-lepton universality in $I ¨ $ decays with the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +428

We present a measurement of the ratio $R_{I^} ¼ = B (I ¨ ^{-} \to I^¼^{-} I^ˉ ½_{I^} ¼ I^½_{I ¨} ) / B (I ¨ ^{-} \to e^{-} I^ˉ ½_{e} I^½_{I ¨} )$ of branching fractions $B$ of the $I ¨ $ lepto…

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…
