Radiative return at NLO and the measurement of the hadronic cross-section

The measurement of the hadronic cross-section in e(+)e(-) annihilation at high luminosity factories using the radiative return method is motivated and discussed. A Monte Carlo generator which simulates the radiative process e(+)e(-) --> gamma+ hadrons at the next-to-leading order accuracy is presented. The analysis is then extended to the description of events with hard photons radiated at very small angle.
