+<hidden TTP04-26  The radiative return and form factors at large $Q^2$ > 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 $\Phi$- or
+ $B$-meson factories. For a detailed understanding and analysis
+ of this reaction, the construction of a Monte Carlo program,
+ PHOKHARA, has been undertaken. A brief overview of
+ the most recent developments is presented, which include the combination
+ of initial- and final-state radiation in the case of two-pion
+ production. Baryon pair production is now included and
+ the pion form factor is extended into the region of large $Q^2$.
+ A model for the kaon
+ form factor is discussed which is
+ fitted to $K^+K^-$ and $K^0\bar{K}^0$ data and which
+ leads to predictions for the $\tau$-decay into $K^-K^0\nu$.
