We study the processes e+e−→ωχbJ(1P) (J=0, 1, or 2) using samples at center-of-mass energies √s=10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb−1 of integrated luminosity, respectively. These data were collected with the Belle II detector during special operations of the SuperKEKB collider above the Υ(4S) resonance. We report the first observation of ωχbJ(1P) signals at √s=10.745 GeV. By combining Belle II data with Belle results at √s=10.867 GeV, we find energy dependencies of the Born cross sections for e+e−→ωχb1,b2(1P) to be consistent with the shape of the Υ(10753) state. These data indicate that the internal structures of the Υ(10753) and Υ(10860) states may differ. Including data at √s=10.653 GeV, we also search for the bottomonium equivalent of the X(3872) state decaying into ωΥ(1S). No significant signal is observed for masses between 10.45 and 10.65 GeV/c2.Received 29 August 2022Accepted 25 January 2023DOI:https://doi.org/10.1103/PhysRevLett.130.091902Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
