Measurement of $J/\psi$ decays into final states $2(\pi^+\pi^-)\pi^0$, $K^+K^-\pi^+\pi^-\pi^0$, $2(\pi^+\pi^-)$ and $K^+K^-\pi^+\pi^-$ with the KEDR detector

Description

Using the $1.32~pb^{-1}$ statistics collected at the $J/\psi$ peak with the KEDR detector at the VEPP-4M $e^+e^-$ collider, we measured the branching fractions of $J/\psi$ meson decays to the final states $2(\pi^+\pi^-)\pi^0$, $K^+K^-\pi^+\pi^-\pi^0$, $2(\pi^+\pi^-)$ and $K^+K^-\pi^+\pi^-$. The results obtained for the decays $J/\psi \to 2(\pi^+\pi^-)\pi^0$, $J/\psi \to K^+K^- \pi^+\pi^-\pi^0$ contradict the measurements performed by other groups in the last century, but agree well with recent results of BABAR and BESIII collaborations.
