Preliminary results on CMD-3 measurement of e+e-→ π+π- cross section
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.
