Abstract

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)2.5 x 10(-3).
