Measurement of [Formula omitted] decays into final states [Formula omitted] and [Formula omitted]

Using the 1.32 [Formula omitted] statistics collected at the [Formula omitted] peak with the KEDR detector at the VEPP-4M [Formula omitted]collider, we measured the branching fractions of [Formula omitted] meson decays to the final states 2( [Formula omitted], [Formula omitted], 2( [Formula omitted]...

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