Abstract

The bottomonium spectrum, consisting of bound states of a b quark and an anti-b quark, provides an excellent laboratory for probing quantum chromodynamics in the non-perturbative regime. While S and P-wave bottomonium states are well studied experimentally, information on D-wave states remains scarce. We search for the D-wave bottomonium states Υ2(1D) and Υ3(1D) via the decay of a vector bottomonium-like state Υ(10753) in the reaction e+e− → π+π−Υ(1D), using 19.6 fb−1 of data collected with the Belle II detector at center-of-mass energies, 10.701, 10.745, and 10.805 GeV, in the vicinity of the Υ(10753) resonance. No significant signals are observed. We set upper limits at the 90% credibility..
