Abstract
The ψ(2S) total decay width, partial widths to hadrons, μ+μ−, π+π−J/ψ final states and corresponding branching ratios are measured with a scan experiment in the vicinity of ψ(2S) resonance at the BES. The preliminary results give much improved accuracies compared with existing data. Also reported are the branching ratios for ψ(2S) to τ‐pair and radiative decays.
