[en] The cross sections for the processes e"+e"− → 2(π"+π"−π"0) and e"+e"− → 3(π"+π"−) at c.m. energies in the range of 1.5–2 GeV were measured with the aid of the CMD-3 detector at the VEPP-2000 collider of the Budker Institute of Nuclear Physics (Novosibirsk, Siberian Branch, Russian Academy of Sciences). The integrated luminosity in the respective experiment was 22 pb"−"1

[en] Since 2010 the CMD-3 detector has been collecting data at the e⁺e⁻ collider VEPP-2000 at Budker Institute of Nuclear Physics. CMD-3 is a general purpose detector designed to study e⁺e⁻ annihilation into hadrons in the wide energy range √s = 0.3−2GeV. The barrel electromagnetic calorimeter of the detector has a thickness equal to 13.5X₀ and consists of two subsystems: closest to the beam pipe is the Liquid Xenon calorimeter (LXe) and the outer one is based on CsI scintillation crystals (CsI). The design of the LXe calorimeter and its current performance are presented

[en] A recent result of the cross section measurement of the process $e^{+}{e}^{-<!--\; ???\; -->}\to <!--\; ???\; -->K_S{K}^{\pm <!--\; ??\; -->}{\mathrm{\pi <!--\; ??\; -->}}^{\mp <!--\; ???\; -->}$ at $e^{+}{e}^{-<!--\; ???\; -->}$ collider VEPP-2000 is presented using a data sample of the ∼150 pb⁻¹ integrated luminosity collected with the CMD-3 detector. The processes with charged kaons in multi hadron events attract special interest, because they impact strongly on studies of light quark hadronization, isospin symmetry, and strange meson spectroscopy. Experimental results of $e^{+}{e}^{-<!--\; ???\; -->}\to <!--\; ???\; -->K_S{K}^{\pm <!--\; ??\; -->}{\mathrm{\pi <!--\; ??\; -->}}^{\mp <!--\; ???\; -->}$ cross section are presented in a broad energy range covered by the VEPP-2000 and compared to earlier measurements. A study of the production dynamics confirms the dominance of neutral ${KK}^{\ast <!--\; ???\; -->}(892)$ intermediate state. (paper)

[en] Since December 2010 the CMD-3 detector has taken data at the electron-positron collider VEPP-2000. The collected data sample corresponds to an integrated luminosity of 60 pb⁻¹ in the c.m. energy from 0.32 up to 2 GeV. The preliminary results of the luminosity measurement are presented in various energy ranges. The current accuracy for integrated luminosity is estimated to be 1%

[en] The barrel electromagnetic calorimeter of the CMD-3 detector consists of two subsystems: the Liquid Xenon calorimeter and the calorimeter based on CsI scintillation crystals. Its structure and main characteristics are presented. The energy calibration procedures of the combined calorimeter are described

[en] The structure of the barrel calorimeter of the CMD-3 detector is presented in this work. The procedure of energy calibration of the calorimeter and the method of photon energy restoration are described. The distinctive feature of this barrel calorimeter is its combined structure; it is composed of two coaxial subsystems: a liquid xenon calorimeter and a crystalline CsI calorimeter. The calorimeter spatial resolution of the photon conversion point is about 2 mm, which corresponds to an angular resolution of ∼6 mrad. The energy resolution of the calorimeter is about 8% for photons with energy of 200 MeV and 4% for photons with energy of 1 GeV

[en] We report preliminary results on the cross section of the process e"+e"− → φ(1020)η measured at 30 center-of-mass energy points in the range from 1.59 up to 2.0 GeV. Data analysis is based on the integrated luminosity of 22 pb"−"1 collected with the CMD-3 detector in 2011–2012. The obtained cross section agrees with the BaBar measurement and has better statistical accuracy.

[en] Experiments with the CMD-3 detector at the VEPP-2000 electron–positron collider in the range of center of mass collision energies from 0.32 to 2 GeV have been performed since December 2010. The amount of accumulated data corresponds to an integrated luminosity of about 60 pb^-1. The resultsof a preliminary analysis are presented for the following annihilation channels: e⁺e^- → 3(π⁺π^-), 2(π⁺π^-π⁰), K⁺K^-π⁺π^-, K⁺K^-, $p\stackrel{¯<!--\; ??\; -->}{p}$, and π⁺π^-. Since processes of electron–positron annihilation that involve the production of multihadron states proceed through several intermediate states, their analysis is necessary for the correct description of the emission-angle and invariant-mass distributions of product particles.

[en] Since December 2010, the CMD-3 detector has collected data at the electronpositron collider VEPP-2000. The sample of the accumulated data corresponds to about 60 pb"−"1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e"+e"− annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.
