[en] Regular data taking with the CMD-3 at the electron-positron collider VEPP-2000 is under way since 2010. The collected data sample corresponds to about 200 inverse picobarns of integrated luminosity per detector in the energy range from 0.32 up to 2 GeV, with a goal to collect about 1 fb⁻¹ during next five years. Some of the recent results from the CMD-3 detector are discussed.

[en] A study of hadron production at the nucleon-antinucleon threshold has been performed with the CMD-3 detector at the VEPP-2000 e⁺e⁻ collider. A very fast rise with an about 1 MeV width has been observed in the e⁺e⁻→ pp̅ cross section. A sharp drop in the e⁺ e⁻→ 3(π⁺π⁻) cross section has been con?rmed and found to have a width of less than 2 MeV, in agreement with the observed fast rise of the e⁺e⁻→ pp̅ cross section. For the ?rst time a similar sharp drop is demonstrated in the e⁺e⁻→ K⁺ K⁻π⁺π⁻ cross section. The behavior of the e⁺e⁻→ 3(π⁺ π⁻), K⁺ K⁻π⁺π⁻ cross sections cannot be explained by an interference of any resonance amplitude with continuum, therefore this phenomenon cannot be due to a narrow near-threshold resonance. No such structure has been observed in the e⁺e⁻→ 2(π⁺π⁻) cross section.

[en] A large data sample of e⁺e^-→ 4π collected by the CMD-3 experiment at the VEPP-2000 e⁺ e⁻ collider allowed for an amplitude analysis of the process e⁺e⁻→ 4π in the center-of-mass energy range 900–2000 MeV. Various intermediate components were distinguished and dominance of the ωπ⁰ and a₁π amplitudes has been proved.

[en] A search for the process e⁺e⁻→ D^*0(2007) has been performed with the CMD-3 detector at the VEPP-2000 e⁺e⁻-collider. Two main decay modes of the D^*0(2007) decay, D⁰π⁰ and D⁰γ, followed by D⁰ → K⁺π⁻π⁺π⁻are used in this analysis. With an integrated luminosity of 3.7 pb⁻¹ collected at the center-of-mass energy E_c.m. =2006.62 MeV our preliminary upper limit is B_{D*⁰→e+ e−}<1.6× 10⁻⁶ at 90%C.L.

[en] The process e⁺ e⁻→ K⁺ K⁻π⁰ has been studied in the center-of-mass energy range from 1.2 to 2 GeV using a 80.6 pb⁻¹ data sample collected with the CMD-3 detector at the electron-positron collider VEPP-2000. Preliminary results of the cross-section measurement are presented.

[en] The cross section of the process e⁺ e⁻→ K_S K_L π⁰ has been studied with the CMD-3 detector at the VEPP-2000 electron-positron collider in the center-of-mass energy range from 1.1 to 2 GeV. Preliminary results on the total cross section of the process are presented.

[en] The preliminary results of measurement of the e⁺ e⁻ → π⁺π⁻π⁰ cross section in the 1.05–2 GeV center-of-mass energy range with 30 pb^–1 of experimental data collected using the CMD-3 detector are presented. The parameters of resonant states ω(1420) and ω(1650) are obtained.

[en] The cross section of the process e⁺e⁻→ π⁺π⁻π⁺π⁻ has been measured using an integrated luminosity of 17 pb⁻¹ collected with the CMD-3 detector in the center-of-mass energy range 650-1000 MeV. High-precision measurements of various hadronic cross sections are of great interest in relation with the problem of the muon anomalous magnetic moment g-2. This measurement can be also used to test the relation between the cross section of e⁺e⁻→ π⁺ π⁻π⁺ π⁻ and the spectral function for the τ⁻→ π⁻π⁰π⁰π⁰ decay predicted by the conservation of vector current (CVC).

[en] Existing Monte-Carlo generators with radiative corrections to the e⁺e^-→π⁺π^- process are usually developed under the assumption that pions can be treated as pointlike particles. We study the e⁺e^-→π⁺π^-γ process with final-state radiation and test this assumption using simulated events from the MCGPJ generator based on the scalar QED hypothesis. In order to increase a fraction of events with FSR, the analysis was performed in the energy region to the left from the ρ-meson peak (660÷785 MeV) that is based on the integrated luminosity of about 8.4 pb^-1. The experimental data for the photon energy spectrum agree with the simulation results at 1% level.

[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)
