The KLOE Experiment at the π factory DAPdblNE has measured the cross section σ(e+e- → π+ π-γ) using two different selection schemes: requiring the photon emission at small polar angle and detecting the photon at large polar angle in the calorimeter. Using a theoretical radiator function we extract the pion form factor and obtain the π π contribution to the anomalous magnetic moment of the muon. Results presented here come from the analysis of 240 pb-1 collected in 2002, with improved systematic uncertainty with respect to the published KLOE analysis. We also include an update of the previous analysis.

Abstract
The KLOE Experiment at the π factory DAPdblNE has measured the cross section σ(e+e- → π+ π-γ) using two different selection schemes: requiring the photon emission at small polar angle and detecting the photon at large polar angle in the calorimeter. Using a theoretical radiator function we extract the pion form factor and obtain the π π contribution to the anomalous magnetic moment of the muon. Results presented here come from the analysis of 240 pb-1 collected in 2002, with improved systematic uncertainty with respect to the published KLOE analysis. We also include an update of the previous analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
