====== TTP01-26 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 $e^+ e^- \to \gamma+hadrons$ 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. |**German Rodrigo** | |** Acta Phys. Polon.
