Abstract
Using data collected in the Belle experiment at the KEKB asymmetric-energy e+e- collider we search for transitions (4S)→ηb(1S)ω, (5S)→ηb(1S)ω and (5S)→ηb(2S)ω. No significant signals are observed and we set 90% confidence level upper limits on the corresponding visible cross sections: 0.2 pb, 0.4 pb and 1.9 pb, respectively. ? 2020 authors.
