Using the KEDR detector at VEPP-4M $e^+e^-$ collider, we have measured values of $R_{\text{uds}}$ and $R$ seven points center-of-mass energy between 3.12 3.72 GeV. The total achieved accuracy is about or better than $3.3\%$ most with a systematic uncertainty $2.1\%$. At moment it accurate measurement $R(s)$ in this range.

We present the analysis of all KEDR data on determination J/ψ and ψ(2S) masses. The comprise six scans seven which were performed at VEPP-4M e+e− collider in 2002–2008. beam energy was determined using resonance depolarization method. detector accelerator conditions during very different that increases reliability averaged results. accounts for partial correlations systematic uncertainties following mass values obtained:MJ/ψ=3096.900±0.002±0.006 MeV,Mψ(2S)=3686.099±0.004±0.009 MeV. These...

We report the final results of a study ψ(3770) meson using data sample collected with KEDR detector at VEPP-4M electron–positron collider. The analysis takes into account interference between resonant and nonresonant DD¯ production, where latter is related to part energy-dependent form factor FD. vector dominance approach several empirical parameterizations have been tried for FDNR(s). Our mass total width areM=3779.2−1.7+1.8−0.7+0.5−0.3+0.3MeV,Γ=24.9−4.0+4.6−0.6+0.5−0.9+0.2MeV, first,...

A high-precision determination of the main parameters \psi(2S) resonance has been performed with KEDR detector at VEPP-4M e^{+}e^{-} collider in three scans -- \psi(3770) energy range. Fitting dependence multihadron cross section vicinity we obtained mass value M = 3686.114 +- 0.007 0.011 ^{+0.002}_{-0.012} MeV and product electron partial width by branching fraction into hadrons \Gamma_{ee}*B_{h} 2.233 0.015 0.037 0.020 keV. The third error quoted is an estimate model result due to...

The present work continues a series of the KEDR measurements $R$ value that started in 2010 at VEPP-4M $e^+e^-$ collider. By combining new data with our previous results this energy range we measured values $R_{\text{uds}}$ and nine center-of-mass energies between 3.08 3.72 GeV. total accuracy is about or better than $2.6\%$ most points systematic uncertainty $1.9\%$. Together precise measurement 1.84-3.05 GeV, it constitutes detailed high-precision near charmonium production threshold.

Using the inclusive photon spectrum based on a data sample collected at $J/\psi$ peak with KEDR detector VEPP-4M $e^+e^-$ collider, we measured rate of radiative decay $J/\psi\to\gamma\eta_{\rm c}$ as well $\eta_{\rm mass and width. Taking into account an asymmetric lineshape obtained $\Gamma^0_{\gamma\eta_{\rm c}}=2.98\pm0.18 \phantom{|}^{+0.15}_{-0.33}$ keV, $M_{\eta_{\rm c}} = 2983.5 \pm 1.4 \phantom{|}^{+1.6}_{-3.6}$ MeV/$c^2$, $\Gamma_{\eta_{\rm 27.2 3.1 \phantom{|}^{+5.4}_{-2.6}$ MeV.
