Abstract

We have measured several branching ratios for ψ′ decay using the data collected by the FNAL E835 experiment during the year 2000, obtaining B(ψ′ → e⁺e^-) = 0.0068 ± 0.0001 ± 0.0004, B(ψ′ → J/ψπ⁺π^-) = 0.292 ± 0.005 ± 0.018, B(ψ′ → J/ψπ⁰π⁰) = 0.167 ± 0.005 ± 0.014, and B(ψ′ → J/ψη) = 0.028 ± 0.002 ± 0.002. We also present a measurement of the dipion mass distribution in the decays ψ′ → J/ψππ.
