Update of the e^+e^-\toπ^+π^- cross section measured by SND detector in the energy region 400<\sqrt{s}<1000 MeV

Abstract

The corrected cross section of the e^+e^-\toπ^+π^- process measured in the SND experiment at the VEPP-2M e^+e^- collider is presented. The update is necessary due to a flaw in the e^+e^-\toπ^+π^- and e^+e^-\toμ^+μ^- Monte Carlo events generators used previously in data analysis.
