Abstract

We report the first observation of Υ(10860)→Υ(1,2,3S) π0π0 decays. The neutral partner of the Zb±(10610), the Zb0(10610) decaying to Υ(2,3S)π0, is observed for the first time with a 6.5σ significance using a Dalitz analysis of Υ(10860)→Υ(2,3S) π0π0 decays. The results are obtained with a 121.4 fb-1 data sample collected with the Belle detector at the Υ(10860) resonance at the KEKB asymmetric-energy e+e- collider.

N2 - We report the first observation of Υ(10860)→Υ(1,2,3S) π0π0 decays. The neutral partner of the Zb±(10610), the Zb0(10610) decaying to Υ(2,3S)π0, is observed for the first time with a 6.5σ significance using a Dalitz analysis of Υ(10860)→Υ(2,3S) π0π0 decays. The results are obtained with a 121.4 fb-1 data sample collected with the Belle detector at the Υ(10860) resonance at the KEKB asymmetric-energy e+e- collider.
