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 0.35π<0.95GeV2. We calculate the hadronic contribution to the muon anomaly for the given mass range: aμ=388.7+/-0.8stat+/-3.5syst+/-3.5thFile in questo prodotto:
