Abstract
We study the processes e(+)e(-)+ omega chi(bJ)(1P) (J = 0, 1, or 2) using samples at center-of-mass energies p = 10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb(-1) of integrated luminosity, ffiffis respectively. These data were collected with the Belle II detector during special operations of the SuperKEKB collider above the gamma(4S) resonance. We report the first observation of omega chi(bJ)(1P) signals at p = 10.745 GeV. By combining Belle II data with Belle results at ffis ffi ffiffis p = 10.867 GeV, we find energy dependencies of the Born cross sections for e(+)e(-)+ omega chi(b1;b2)(1P) to be consistent with the shape of the gamma(10753) state. These data indicate that the internal structures of the gamma(10753) and gamma(10860) states may ffiffidiffer. Including data at root s = 10.653 GeV, we also search for the bottomonium equivalent of the X(3872) state decaying into omega gamma(1S). No significant signal is observed for masses between 10.45 and 10.65 GeV/c(2).
