Preliminary results of measurements of hadronic cross sections with the CMD-3 detector at the VEPP-2000 electron–positron collider

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 -, \(p\bar p\), 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.
