Abstract

Using the 1.32 statistics collected at the peak with the KEDR detector at the VEPP-4M collider, we measured the branching fractions of meson decays to the final states 2(, , 2( and . The results obtained for the decays 2(, contradict the measurements performed by other groups in the last century, but agree well with recent results of BABAR and BESIII collaborations.
