Search for the lepton-flavor-violating $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{\mp}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +447

We present the result of a search for the charged-lepton-flavor violating decays $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{-}$ , where $ℓ$ is a muon or an electron, using a data sampl…

Measurement of the branching fraction, polarization, and time-dependent $C P$ asymmetry in $B^{0} \to I ¨ ^{+} I ¨ ^{-}$ decays and constraint on the CKM angle $I ¨ _{2}$

Belle II Collaboration, I. Adachi, L. Aggarwal +377

We present a measurement of the branching fraction and fraction of longitudinal polarization of $B^{0} \to I ¨ ^{+} I ¨ ^{-}$ decays, which have two $I ¨ ^{0}$ 's in the final state. We also meas…
