Title: Search for Invisible Decay of the {upsilon}(1S)

Abstract

We report results of a search for the invisible decay of the {upsilon}(1S) via the {upsilon}(3S){yields}{pi}{sup +}{pi}{sup -}{upsilon}(1S) transition using a data sample of 2.9 fb{sup -1} at the {upsilon}(3S) resonance. The data were collected with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} 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){yields}invisible)<2.5x10{sup -3}.
