Study of $B^{+} \to I^¼^{+} I^½_{I^} ¼$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay $B^{+} \to I^¼^{+} I^½_{I^} ¼$ . This work presents the first $B^{+} \to I^¼^{+} I^½_{I^} ¼$ result using Belle~II data, an updated Be…

Study of $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ (h = I ¨ , K, p)$ via initial-state radiation at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +417

Using a data sample of 427.9 fb $^{- 1}$ collected by the Belle~II detector at or near the $I^¥ (4 S)$ and $I^¥ (10753)$ resonances, the cross sections for $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ $ $(h=Ï/K…
