Table 1

Summary of data samples (in the unit of ) of the particles below threshold collected by Belle, BaBar, and CLEO collaborations. The data in the 5th column correspond to total number of the particles, including events from hadronic dipion transitions between upsilons , where branching ratios for the dipion decays , and , are %, %, %, and %, respectively [4].
