We search for the and processes at a center-of-mass energy of 10.745 GeV, which is close to the peak of the state. We use data collected by the Belle II experiment during a special run, corresponding to an integrated luminosity of . We reconstruct decays and use the 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 limit is the result of a combination of this analysis and a previous search using full reconstruction.
