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…

Measurement of $Γ_{ee} \times B_{μμ}$ for $ψ (2 S)$ meson

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

The product of the electronic width of the $ψ (2 S)$ meson and the branching fraction of its decay to the muon pair was measured in the $e^{+} e^{-} \to ψ (2 S) \to μ^{+} μ^{-}$ process…

Measurement of $R$ between 1.84 and 3.05 GeV at the KEDR detector

V. V. Anashin, V. M. Aulchenko, E. M. Baldin +75

Using the KEDR detector at the VEPP-4M $e^{+} e^{-}$ collider, we have determined the values of $R$ at thirteen points of the center-of-mass energy between 1.84 and 3.05 GeV. The achiev…

Measurement of $R_{uds}$ and $R$ between 3.12 and 3.72 GeV at the KEDR detector

V. V. Anashin, V. M. Aulchenko, E. M. Baldin +75

Using the KEDR detector at the VEPP-4M $e^{+} e^{-}$ collider, we have measured the values of $R_{uds}$ and $R$ at seven points of the center-of-mass energy between 3.12 and 3.72…
