Search for the decay $B^{+} \to K^{+} τ^{+} τ^{-}$ using data from the Belle and Belle II experiments

Belle, Belle II Collaborations, : +446

We report a search for the rare decay $B^{+} \to K^{+} τ^{+} τ^{-}$ using $1.2 \times 1 0^{9}$ $Υ (4 S)$ mesons produced near threshold in electron-positron collisions and colle…

Measurement of time-dependent $C P$ asymmetries in $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-} I^^{3}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +350

We present a measurement of the time-dependent $C P$ asymmetry in $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-} I^^{3}$ decays using a data set of 365 fb $^{- 1}$ recorded by the Belle II experim…
