TTP02-25 Precision measurement of the hadronic cross-section through the radiative return method

Electron–positron annihilation into hadrons plus an energetic photon from initial-state radiation allows the hadronic cross-section to be measured over a wide range of energies at high luminosity meson factories. Weighted integrals over this cross-section are a decisive input for electroweak precision tests. A Monte Carlo event generator called PHOKHARA has been developed, which simulates e^+ e^- \to hadrons + photon(s) at the NLO accuracy. The latest tests and upgrades are presented in this paper.
