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…
