gCross Section Measurements at Phi- and B-Meson-Factories Through the

Radiative Returnh

Abstract:

 

Recent theoretical results on cross section measurements at Phi- and B-meson-factories

through the radiative return will be presented. This includes a discussion of the production of

two-, three- and four-pion final states, of kaon pairs. Possibilities for the measurement of

the nucleon form factors through an analysis of angular distributions will be described.

The role of higher order radiative corrections will be discussed and the status of the Monte Carlo

generator PHOKHARA will be reported.
