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 the $C P$ asymmetry in $D^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ decays at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +400

We measure the time- and phase-space-integrated $C P$ asymmetry $A_{C P}$ in $D^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ decays reconstructed in $e^{+} e^{-} \to c c ˉ$ events collected by the Belle II experim…

Determination of $∣ V_{c b} ∣$ using $B \to D ℓ I^½_{ℓ}$ Decays at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +407

We present a determination of the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{c b} ∣$ from the decay $B \to D ℓ I^½_{ℓ}$ using a $365 fb^{- 1}$ $e^{+} e^{-} \to I^¥ (4 S) \to B B ˉ$ …

Model-agnostic likelihood for the reinterpretation of the $B^{+} \to K^{+} I^½ I^ˉ ½$ measurement at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +374

We recently measured the branching fraction of the $B^{+} \to K^{+} I^½ I^ˉ ½$ decay using 362fb $^{- 1}$ of on-resonance $e^{+} e^{-}$ collision data under the assumption of Standar…
