摘要：

The cross section of the process e(+)e(-) -> 3(pi(+)pi(-)) has been measured using a data sample of 22 pb(-1) collected with the CMD-3 detector at the VEPP-2000 e(+)e(-) collider. 7956 signal events are selected in the center-of-mass energy range 1.5-2.0 GeV. The measured cross section exhibits a sharp drop near the p (p) over bar threshold. A first study of dynamics of six-pion production has been performed. (c) 2013 Published by Elsevier B.V.
