The KLOE experiment at the DA?NE ?-factory has performed a new precise measurement of the pion form factor using Initial State Radiation events, with photons emitted at small polar angle. Results based on an integrated luminosity of 240 pb-1 and extraction of the ?? contribution to a? in the mass range [0.35,0.95] GeV2 are presented, the systematic uncertainty is reduced with respect to the published KLOE result.

Abstract
The KLOE experiment at the DA?NE ?-factory has performed a new precise measurement of the pion form factor using Initial State Radiation events, with photons emitted at small polar angle. Results based on an integrated luminosity of 240 pb-1 and extraction of the ?? contribution to a? in the mass range [0.35,0.95] GeV2 are presented, the systematic uncertainty is reduced with respect to the published KLOE result.File in questo prodotto:
