摘要
We search for the $e^+e^-\to\eta_b(1S)\omega$ and
$e^+e^-\to\chi_{b0}(1P)\omega$ processes at a center-of-mass energy of 10.745
GeV, which is close to the peak of the $\Upsilon(10753)$ state. We use data
collected by the Belle II experiment during a special run, corresponding to an
integrated luminosity of $9.8\,\mathrm{fb}^{-1}$. We reconstruct
$\omega\to\pi^+\pi^-\pi^0$ decays and use the $\omega$ 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 $\chi_{b0}(1P)\omega$ limit
is the result of a combination of this analysis and a previous search using
full reconstruction.
