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…

A search for feebly-interacting particles in $B$ decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle $X_{inv}$ , produced in $B^{0} \to D ˉ^{0} X_{inv}$ and $B^{\pm} \to h X_{inv}$ decays, where $h = I ¨ ^{\pm}$ ,…

Study of $I ¨ _{b J} (2 P) \to I ¨ I^¥ (1 S)$ at Belle

Belle Collaboration, Z. S. Stottler, T. K. Pedlar +179

We report a study of the hadronic transitions $I ¨ _{b J} (2 P) \to I ¨ I^¥ (1 S)$ , with $I ¨ \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ , using $28.2 \times 1 0^{6} I^¥ (3 S)$ mesons recorded by the Belle detector. We pres…

Search for lepton-flavor-violating $I ¨ ^{-} \to ℓ^{-} K_{s}^{0}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +419

We present the results of a search for charged-lepton-flavor violating decays $I ¨ ^{-} \to ℓ^{-} K_{S}^{0}$ , where $ℓ^{-}$ is either an electron or a muon. We combine $…
