KLOE first results on hadronic physics
Abstract
The KLOE detector at DAFNE, the Frascati Phi-factory, has collected about 8 millions phi decays in 1999. Measurements of Phi decays into pi0, eta, eta', f0(980), a0(980) and pi+pi-pi0 have been performed with statistical accuracy better than previously in a single detector, as well as new decay modes. Phi radiative decays can clarify the nature of f0 and a0 (are they 4 quark states?) and measure the eta-eta' mixing angle. Analysis of Phi->pi+pi-pi0 allows us to extract the possible existence of direct decay in addition to the dominant rho-pi mode and to obtain a precise measurement of the rho parameters such as the mass difference between the charged and neutral rho, previously never seen.
