Experimental study of X-b(2P)->pi pi X-b(1P) Academic Article uri icon


  • We have searched for the di-pion transition b(2P) b(1P) in the CLEO III sample of (3S) decays in the exclusive decay chain: (3S)b(2P), b(2P) b(1P), b(1P)(1S), (1S)+-. Our studies include both +- and 00, each analyzed both in fully-reconstructed events and in events with one pion undetected. We show that the null hypothesis is not substantiated. Under reasonable assumptions, we find the partial decay width to be (b(2P)b(1P))=(0.830.220. 080.19)keV, with the uncertainties being statistical, internal CLEO systematics, and common systematics from outside sources. 2006 The American Physical Society.
