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…

Kink Finder at Belle II

Denis Bodrov, Xinping Xu, Dmitrii Gavrilov +27

We present a track-finding algorithm for the Belle II experiment that specifically targets so-called kinks: signatures of charged particles decaying or scattering in-flight in the…

Study of $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^¥ (1 D)$ at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +404

The bottomonium spectrum, consisting of bound states of a $b$ quark and an anti- $b$ quark, provides an excellent laboratory for probing quantum chromodynamics in the non-perturbati…
