Search for Invisible Decay of the Υ(1S)

O. Tajima, H. Hayashii, M. Hazumi, K. Inami et autres

We report results of a search for the invisible decay of the Υ(1S) via the Υ(3S)→π+π-Υ(1S) transition using a data sample of 2.9 fb^{-1} at the Υ(3S) resonance. The data were collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. …
