چکیده انگلیسی
The e+e− hadronic cross section is measured at the Frascati ϕ-factory DAΦNE with the KLOE detector using initial state radiation (ISR). Two different analyses have been developed for the channel e+e−→π+π−γ, which differ by the photon polar angle direction. The so-called small angle analysis, in which the photon is not detected, has been published with a total error on the pion form factor of 1.3%. In a second approach, where the photon is emitted at large polar angles, the mass region below 0.35 GeV2 becomes accessible. The status and the prospects of these analyses are reported.
