In the fixed energy environment of the e +e - collider DAΦNE, KLOE can measure the cross section of the process e +e - → hadrons as a function of the hadronic system energy using the radiative return.

Abstract
In the fixed energy environment of the e +e - collider DAΦNE, 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 - → π → π +π - is the dominating hadronic process. We report here on the status of the analysis for the e +e - → π +π - γ channel, which allows to obtain a preliminary measurement of the pion form factor using an integrated luminosity of ∼ 73pb -1.File in questo prodotto:
