Measurement of the e + e - → π+π- cross section with the CMD-2 detector in the 370-520-MeV energy range
The results of the experiment on the measurement of the e + e - → π+π- cross section in a cm energy range of 370-520 MeV are presented. The systematic measurement error is equal to 0.7%. In the vector dominance model, the pion electromagnetic radius is calculated using all the CMD-2 data on the pion form factor. The cross section for the production of a muon pair is measured in the energy range of the experiment. © Nauka/Interperiodica 2006.
