Branching fractions for transitions of ψ(2S) to J/ψ

Branching fractions for transitions of ψ(2S) to J/ψ

We report determination of branching fractions for the decays ψ(2S)→h+J/ψ, where h=any, π+π-, π0π0, η, π0, and γγ through χc0,1,2. These measurements use 27M ψ(2S) decays produced in e+e- collision data collected with the CLEO detector. The resulting branching fractions and ratios thereof improve up...
