PHOKHARA, the radiative return and the $(g-2{)}_{\mu }$ puzzle

Abstract

The radiative return has proven to be a competitive method for the precise measurement of the hadronic cross section, detailed studies of hadronic interactions, and even discoveries of new resonances. The most recent and future devolopments of the Monte Carlo event generator PHOKHARA are highlighted, and the impact of the radiative return measurements on the $(g-2{)}_{\mu }$ puzzle is discussed.
