Update of the e^+e^-toπ^+π^- cross section measured by SND detector in the energy region 400<sqrt{s}<1000 MeV
read the original abstract
The corrected cross section of the e^+e^-\to\pi^+\pi^- 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^-\to\pi^+\pi^- and e^+e^-\to\mu^+\mu^- Monte Carlo events generators used previously in data analysis.
