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(

contradict the measurements performed by other groups in the last century, but agree well with recent results of BABAR and BESIII collaborations.
