A precise new KLOE measurement of F with ISR events and determination of ππ contribution to a for [0.35, 0.95] GeV 2
Abstract
The KLOE experiment at the DAΦNE ϕ-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 ππ contribution to a in the mass range [0.35, 0.95] GeV 2 are presented, the systematic uncertainty is reduced with respect to the published KLOE result.
