A Method for the Direct Absolute Measurement of J/ψ Decay with ψ(3686) Data Set
To take the full advantage of the ψ(3686) data set collected at e+e- collider at τ-charm energy region, a tag method is developed to directly measure the J/ψ meson decay branching fractions absolutely. The J/ψ meson decay can be measured with the J/ψ sample tagged by the two soft charged pions from...
