摘要
We report measurements of the e^+e^- → BB̅, BB̅^*, and
B^*B̅^* cross sections at four energies, 10653, 10701, 10746 and 10805
MeV, using data collected by the Belle II experiment. We reconstruct one B
meson in a large number of hadronic final states and use its momentum to
identify the production process. In the first 2-5 MeV above B^*B̅^*
threshold, the e^+e^- → B^*B̅^* cross section increases rapidly.
This may indicate the presence of a pole close to the threshold.
