Abstract 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{sup -1}. The resultsof a preliminary analysis are presented for the following annihilation channels: e{sup +}e{sup -} → 3(π{sup +}π{sup -}), 2(π{sup +}π{sup -}π{sup 0}), K{sup +}K{sup -}π{sup +}π{sup -}, K{sup +}K{sup -}, pp̄, and π{sup +}π{sup -}. 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.
