+   <hidden TTP04-07  The radiative return at Phi- and B-factories: FSR for muon pair production at next-to-leading order >   Muon pair production through the radiative return is of importance for a
+ measurement of the hadronic production cross section in two ways: it provides
+ an independent calibration and it may give rise to an important background for
+ a measurement of the pion form factor. With this motivation the Monte Carlo
+ event generator PHOKHARA is extended to include next-to-leading order radiative
+ corrections to the reaction $e^+e^-\to \mu^+\mu^-\gamma$. Furthermore, virtual
+ ISR corrections to FSR from pions are introduced, which extends the
+ applicability of the generator into a new kinematical regime. Finally, the
+ effect of photon vacuum polarization is introduced into this new version of the
+ generator.
