In the fixed energy environment of the e(+)e(-) collider DAPhiNE, KLOE can measure the cross section of the process e(+)e(-) --> hadrons as a function of the hadronic system energy using the radiative return. At energies below 1 GeV, e(+)e(-) --> rho --> pi(+)pi(-) is the dominating hadronic process. We report here on the status of the analysis for the e(+)e(-) --> pi(+)pi(-)gamma channel, which allows to obtain a preliminary measurement of the pion form factor using an integrated luminosity of similar to 73 pb(-1).

Abstract
In the fixed energy environment of the e(+)e(-) collider DAPhiNE, KLOE can measure the cross section of the process e(+)e(-) --> hadrons as a function of the hadronic system energy using the radiative return. At energies below 1 GeV, e(+)e(-) --> rho --> pi(+)pi(-) is the dominating hadronic process. We report here on the status of the analysis for the e(+)e(-) --> pi(+)pi(-)gamma channel, which allows to obtain a preliminary measurement of the pion form factor using an integrated luminosity of similar to 73 pb(-1).File in questo prodotto:
