MESON decay ,MEASUREMENT - Abstract
Using the 1.32 pb - 1 statistics collected at the J / ψ peak with the KEDR detector at the VEPP-4M e + e - collider, we measured the branching fractions of J / ψ meson decays to the final states 2( π + π -) π 0 , K + K - π + π - π 0 , 2( π + π -) and K + K - π + π - . The results obtained for the decays J / ψ → 2( π + π -) π 0 , J / ψ → K + K - π + π - π 0 contradict the measurements performed by other groups in the last century, but agree well with recent results of BABAR and BESIII collaborations.
