Abstract
KLOE uses the radiative return to measure cross section σ(e+e- → π+ π-γ) at the electron-positron collider DAΦNE. Divinding by a theoretical radiator function, we obtain the cross section σ(e+e- → π+ π-γ) for the mass range 0.35 < sπ < 0.95 GeV2. We calculate the hadronic contribution to the muon anomaly for the given mass range: aμ = 388.7 ± 0.8stat ± 3.5syst ± 3.5th.File in questo prodotto:
