Perspectives for the Radiative Return at Meson Factories *

The measurement of the pion form factor and, more generally, of the cross section for electron–positron annihilation into hadrons through the radiative return has become an important task for high luminosity colliders such as the Φor B-meson factories. This quantity is crucial for predictions of the hadronic contributions to (g − 2)μ, the anomalous magnetic… CONTINUE READING
