我们使用质心能量为 10.745 和 10.805 GeV（分别对应于 1.6、9.8 和 1.6、9.8 和 积分光度）的样本来研究过程（1 或 2）。这些数据是在 SuperKEKB 对撞机在 ϒ(4S) 共振上方进行特殊操作期间用 Belle II 探测器收集的。我们报告了第一次观察到的信号。通过将 Belle II 数据与 Belle 结果相结合，我们发现 Born 截面的能量依赖性与 ϒ(10753) 态的形状一致。这些数据表明 ϒ(10753) 和 ϒ(10860) 状态的内部结构可能不同。包括 的数据，我们还搜索衰变成 ωϒ(1S) 的状态的底鎓等价物。对于 10.45 和 10.45 之间的质量，没有观察到明显的信号。
We study the processes(, 1, or 2) using samples at center-of-mass energies, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, andof 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 ofsignals at. By combining Belle II data with Belle results at, we find energy dependencies of the Born cross sections forto 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, we also search for the bottomonium equivalent of thestate decaying into ωϒ(1S). No significant signal is observed for masses between 10.45 and.
