Status of experiments and recent results from CMD-2 detector at VEPP-2M

Abstract The Cryogenic Magnetic Detector (CMD-2) is shortly described. Preliminary results for the cross sections of e + e − annihilation into hadrons and leptons are presented in the c.m. energy range from 0.37 to 1.39 GeV. The total integrated luminosity of about 26 pb −1 has been collected. The new results for the ϱ and ω meson parameters are reported. The major decay modes of the f meson as well as its rare decays have been observed. The tagged kaons and η mesons in f meson decays were used to look for some decay modes of K S o and η mesons.
