Description

The Belle collaboration recently reported the discovery of the p-wave Bottomonium singlets, hb(1P) and hb(2P), the surprising observation of resonant substructure in Y(5S) --> pi+pi-Y(nS), hb(mP) (n=1-3, m=1,2), and the first observation of the radiative transition hb(1P) --> gamma etab(1S) in 121.4 1/fb of data collected near the Upsilon(5S) resonance at the KEKB asymmetric-energy e^+e^- collider. We report further studies performed at this energy.
