We report a search for the lepton-flavor-violating decays $τ^{\pm} \to ℓ^{\pm} α$ ~( $ℓ = e, μ$ ), where $α$ is an undetected spin-0 particle, such as an axion-like particle using $73…

Search for a light Higgs boson in single-photon decays of $Υ (1 S)$ using $Υ (2 S) \to π^{+} π^{-} Υ (1 S)$ tagging method

Belle Collaboration, S. Jia, C. P. Shen +210

We search for a light Higgs boson ( $A^{0}$ ) decaying into a $τ^{+} τ^{-}$ or $μ^{+} μ^{-}$ pair in the radiative decays of $Υ (1 S)$ . The production of $Υ (1 S)$ mesons is tagged by $Υ(2S)\to π^+…

Measurement of the branching fraction of $Λ_{c}^{+} \to p ω$ decay at Belle

Belle Collaboration, S. X. Li, L. K. Li +193

Using 980.6 $f b^{- 1}$ of data collected with the Belle detector operating at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we present a measurement of the branching fraction of…

Study of $e^{+} e^{-} \to Υ (1S, 2S) η$ and $e^{+} e^{-} \to Υ (1S) η^{'}$ at $s = 10.866$ GeV with the Belle detector

Belle Collaboration, E. Kovalenko, A. Garmash +179

We report the first observation of the processes $e^{+} e^{-} \to Υ (1S, 2S) η$ at $s = 10.866$ ~GeV with a $10.2 σ$ and $16.5 σ$ significance respectively. The measured Born cross sec…

Study of $χ_{b J} (n P) \to ω Υ (1 S)$ at Belle

Belle Collaboration, A. Abdesselam, I. Adachi +470

We report results from a study of hadronic transitions of the $χ_{b J} (n P)$ states of bottomonium at Belle. The $P$ -wave states are reconstructed in transitions to the $Υ (1 S)$ with…
