New measurement of D0 and D+ meson masses with the KEDR detector

KEDR Collaboration, V. V. Anashin, O. V. Anchugov +117

Using the 4.9 pb $^{- 1}$ statistics collected at the peak of the $ψ (3770)$ resonance with the KEDR detector at the VEPP-4M electron-positron collider, we measured the masses of the…

Measurement of the branching fraction of $J / ψ \to ρ π$ at KEDR

V. V. Anashin, O. V. Anchugov, A. V. Andrianov +91

We present the study of the decay $J / ψ \to ρ π$ . The results are based on of 5.2~million $J / ψ$ events collected by the KEDR detector at the VEPP-4M collider. The branching fr…

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…
