Title: First observation of the Z b 0 ( 10610 ) in a Dalitz analysis of Υ ( 10860 ) Υ ( n S ) π 0 π 0

Abstract

Here, 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 findings 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.
