Preliminary results from BESII's larger dataset
Measured branching ratios of $A(2S)$ decays
Abstract
We report partial wave analysis results for based on BESI events, and find to be dominant in the mass region. Some very preliminary results are presented from the events newly collected at the upgraded BES(BESII). Using the world largest data sample, BES measures branching ratios of radiative and hadronic decays. The preliminary R values measured by BESII in the 2-5 GeV energy region are also presented.
