Abstract:
Existing Monte-Carlo generators with radiative corrections to the e + e - →π + π - process are usually developed under the assumption that pions can be treated as pointlike particles. We study the e + e - →π + π - γ process with final-state radiation and test this assumption using simulated events from the MCGPJ generator based on the scalar QED hypothesis. In order to increase a fraction of events with FSR, the analysis was performed in the energy region to the left from the ρ -meson peak (660÷785 MeV) that is based on the integrated luminosity of about 8.4 pb -1 . The experimental data for the photon energy spectrum agree with the simulation results at 1% level.
