  "abstract": "We have measured the cross section $\\sigma(e^+e^-\\to \\pi^+\\pi^- \\gamma)$ at an energy $W=m_\\phi=1.02$ GeV with the KLOE detector at the electron-positron collider DA$\\Phi$NE. From the dependence of the cross section on the invariant mass of the two-pion system, we extract $\\sigma(e^+e^-\\to \\pi^+\\pi^-)$ for the mass range $0.35<s<0.95$ GeV$^2$. From this result, we calculate the pion form factor and the hadronic contribution to the muon anomaly, $a_\\mu$.",
