Abstract

In the fixed energy environment of the e⁺e^- collider DAΦNE, KLOE can measure the cross section of the process e⁺e^- → hadrons as a function of the hadronic system energy using the radiative return method. At energies below 1 GeV, e⁺e^- → ρ→ π⁺π^- is the dominating hadronic process. We report here on the status of the analysis of the process e⁺e^- → π⁺π^-γ. Some preliminary results on the invariant mass spectrum of the two pion system, obtained from the analysis of 22.6 pb^-1, are presented.
