Abstract: (APS)

We search for the

e^{+} e^{-} \to η_{b} (1 S) ω

and

e^{+} e^{-} \to χ_{b 0} (1 P) ω

processes at a center-of-mass energy of 10.745 GeV, which is close to the peak of the

ϒ (10753)

state. We use data collected by the Belle II experiment during a special run, corresponding to an integrated luminosity of

9.8 {fb}^{- 1}

. We reconstruct

ω \to π^{+} π^{-} π^{0}

decays and use the

ω

meson’s recoil mass to search for the signals. We do not find evidence for either process, and set upper limits on the corresponding Born-level cross sections of 2.5 pb and 7.8 pb, respectively, at the 90% confidence level. The

χ_{b 0} (1 P) ω

limit is the result of a combination of this analysis and a previous search using full reconstruction.
