Description
We consider the branching ratio of Υ(1D)→Υ(1S)ππ, which is related to the ππ spectrum in Υ(2S)→Υ(1S)ππ. Fixing the gluonic contribution to Υ(2S)→Υ(1S)ππ from the ππ spectrum in Υ(2S)→Υ(1S)ππ, we find that the decay rate of Υ(1D)→Υ(1S)ππ can be an order of magnitude larger than the previous calculations. Then, we can have 70 to 90 events of Υ(1D)→Υ(1S)ππ in 106 Υ(3S) decays, which is at the limit of detectability
