Abstract
10.745 GeV, which is close to the peak of the ϒð10753Þ 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 → πþπ−π0 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 χb0ð1PÞω limit is the result of a combination of this analysis and a previous search using full reconstruction.
