Description:
Author(s): P. Krokovny et al. (Belle Collaboration) We report the first observation of Υ (10860)→ Υ (1,2,3 S ) π 0 π 0 decays. The neutral partner of the Z b ± (10610), the Z b 0 (10610) decaying to Υ (2,3 S ) π 0 , is observed for the first time with a 6.5 σ significance using a Dalitz analysis of Υ (10860)→ Υ (2,3 S ) π 0 π 0 decays. The results are obtained with a 121.4 fb -1 d... [Phys. Rev. D 88, 052016] Published Fri Sep 20, 2013
