Searches for charged-lepton-flavor violation in $χ_{b J} (1 P)$ decays

Belle, Belle II Collaborations, : +425

We report the first searches for charged-lepton-flavor violation in decays of $χ_{b J} (1 P)$ ( $J = 0, 1,$ and $2$ ) to a pair of charged leptons using 158 million $Υ (2 S)$ decays collect…

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…

Hardware-Aware Design of a GNN-Based Hit Filtering Algorithm for the Belle II Level-1 Trigger

Greta Heine, Fabio Mayer, Marc Neu +2

The Belle~II experiment operates at high luminosity, where an increasing beam-induced background imposes stringent demands on the hardware Level-1 trigger system, which must operat…
