Open AccessMeasurement of the branching fraction of J/ψ → ρπ at KEDR
We present the study of the decay J/ψ → ρπ. The results are based on of 5.2 million J/ψ events collected by the KEDR detector at the VEPP-4M collider. The branching fractions are measured to be

Open AccessAddendum to: Measurement of Γee(J/ψ) with KEDR detector
The electronic width of the J/ψ meson and its product by the branching fractions of J/ψ meson decay to hadrons and electrons measured with the KEDR detector at the VEPP-4M e+e− collider have been reported in ref....

Open AccessMeasurement of the e+e−→ ηπ+π− cross section with the CMD-3 detector at the VEPP-2000 collider
The cross section of the process e+e−→ ηπ+π− is measured using the data collected with the CMD-3 detector at the VEPP-2000 collider in the center-of-mass energy range from 1.1 to 2.0 GeV. The decay mode η → γγ is...

Open AccessMeasurement of Γee(J/ψ) with KEDR detector
The product of the electronic width of the J/ψ meson and the branching fractions of its decay to hadrons and electrons has been measured using the KEDR detector at the VEPP-4M e+e− collider. The obtained values a...
