Abstract
The CMD-3 detector has been successfully collecting data at the electron-positron collider VEPP-2000 since December 2010. The first scan below 1 GeV for a π+π− measurement was performed in 2013. The collected data sample corresponds to about 18 pb−1 of integrated luminosity in this energy range. Analysis of the e+e−→ π+π− cross section is in progress. Status of this measurement are presented. [ABSTRACT FROM AUTHOR]
