Recent Charmonium Results from BES
Abstract
This paper summarizes recent results obtained from the BES psi(2S) data, which with 3.8 M events, is the world's largest data set. Distributions for psi(2S) -> pi+ pi- J/psi are fit to the Novikov-Shifman model. Preliminary branching fractions are reported for psi(2S) -> gamma f2(1270) and gamma fJ(1710), as well as for decays into states containing an omega or phi. Finally recent measurements of the mass of the chic0 and etac are reported.
