The branching fraction measurements of $J / ψ$ decay into $ρ η$ and $ϕ η$ final states

KEDR Collaboration, V. V. Anashin, O. V. Anchugov +95

We present measurements of the branching fractions for the $J / ψ$ meson decays into the $ρ η$ and $ϕ η$ final states, based on data collected with the KEDR detector at the VEPP-4M col…

Precise measurement of $R_{uds}$ and $R$ between 1.84 and 3.72 GeV at the KEDR detector

V. V. Anashin, O. V. Anchugov, V. M. Aulchenko +86

The present work continues a series of the KEDR measurements of the $R$ value that started in 2010 at the VEPP-4M $e^{+} e^{-}$ collider. By combining new data with our previous results…
