TL;DR: The KLOE experiment at the DA$\Phi$NE $\phi$-factory in Frascati aims to determine the cross section of the dominant contribution of the muon at energies below 1 GeV exploiting the radiative return from the π to the ρ and ρ mesons as mentioned in this paper.
Abstract: The measurement of hadronic cross sections at low centre-of-mass energies is currently attracting much interest because of the r\^o{}le these measurements play in the theoretical evaluation of the anomalous magnetic moment of the muon. The KLOE experiment at the DA$\Phi$NE $\phi$-factory in Frascati aims to determine the cross section of the dominant contribution $e^{+}e^{-} \to \pi^{+}\pi^{-}$ at energies below 1 GeV exploiting the radiative return from the $\phi$ to the $\rho$ and $\omega$ mesons. This method has systematic errors completely different from previous measurements and allows a cross check of existing data in this energy region. The method and results on both the differential cross section for $e^{+}e^{-} \to \pi^{+}\pi^{-}\gamma$ and the total cross section for $e^{+}e^{-} \to \pi^{+}\pi^{-}$ are presented.

TL;DR: In this article, a review of recent results on light meson physics is presented, including the evidence of new states with a mass close to twice the proton mass and a new analysis of the gluonium content of 0.
Abstract: Some recent results on light meson physics are reviewed. The new evidence of low mass scalar mesons together with the improved measurement of the radiative decays in scalar mesons, give new insight into the nature and the structure of the scalar spectrum. The evidence of new states with a mass close to twice the proton mass, and a new analysis of the gluonium content of 0 are also discussed.
