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 Rare $b \to d ℓ^{+} ℓ^{-}$ Transitions at Belle

Belle, Belle II Collaborations, : +393

We present the results of a search for the $b \to d ℓ^{+} ℓ^{-}$ flavor-changing neutral-current rare decays $B^{+, 0} \to (I^\cdot, I ¨ , I ¨ ^{+, 0}, I ¨ ^{+, 0}) e^{+} e^{-}$ and $B^{+, 0} \to (…

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…

Observation of the Electromagnetic Dalitz Transition $h_{c} \to e^{+} e^{-} I^\cdot_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $I ¨ (3686)$ decays and data samples of $e^{+} e^{-}$ collisions with $s$ from 4.130 to 4.780~GeV collected with the BESIII detector, we report th…
