摘要：
We report results of a search for the invisible decay of the Upsilon(1S) via the Upsilon(3S)->pi(+)pi(-)Upsilon(1S) transition using a data sample of 2.9 fb(-1) at the Upsilon(3S) resonance. The data were collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. No signal is found, and an upper limit for the branching fraction at the 90% confidence level is determined to be B(Upsilon(1S)-> invisible)< 2.5x10(-3).
