Spectroscopy of the UPSILON(2S) with the Crystal Ball

Conference ·
OSTI ID:5296855
The Crystal Ball experiment has been taking data at the DORIS II storage ring at DESY/Hamburg on the UPSILON(2S) and UPSILON(1S) resonances since summer 1982. Results on the hadronic transitions between the UPSILON(2S) and the UPSILON(1S) are presented as well as measurements of the radiative decays of the UPSILON(2S) to the chi/sub b/ states in inclusive and exclusive channels. The exclusive UPSILON(2S) ..-->.. ..gamma..chi/sub b/ ..-->.. ..gamma gamma..UPSILON(1S) ..-->.. ..gamma gamma..l/sup +/l/sup -/ sample allows a study of the spins of the chi/sub b/ states. Also discussed is the present status of the zeta(8.3) in the radiative decays of the UPSILON(1S). 22 refs., 14 figs.
