Abstract

Since 2010 the CMD-3 detector has been collecting data at the VEPP-2000 e⁺e⁻ collider. CMD-3 is a general purpose detector designed to study e⁺e⁻ annihilation into hadrons in the center-of-mass (c.m.) energy range from 0.3 up to 2 GeV. Preliminary results for the e⁺e⁻ → 2(π⁺π⁻π⁰) cross section were obtained in the c.m. energy range from 1.5 up to 2 GeV. The analysis is based on a data sample of 22 pb⁻¹.
