摘要：

The e(+)e(-) --> pi(+)pi(-)pi(+)pi(-) cross section has been measured using 5.8 pb(-1) of integrated luminosity collected with the CMD-2 detector at the VEPP-2M collider. Analysis of the data with a refined efficiency determination and use of both three- and four-track events allowed doubling of a data sample and reduction of systematic errors to 5-7%.
