Light scalar mesons at KLOE

The scalar mesons of mass below 1 GeV have been studied with the KLOE detector at the Frascati φ‐factory DAΦNE, through the radiative decays of the φ(1020). The f0(980) has been studied in the decays φ→π0π0γ and φ→π+π−γ looking also for a possible signal of the σ(600), while for the a0(980) the φ→ηπ0γ decay has been exploited. The branching ratios of these decays have been measured, and the relevant parameters of the scalar mesons have been extracted from the fit of the invariant mass distributions of the pseudoscalar mesons in the final states. Moreover an upper limit for the branching ratio of φ→(a0/f0)→K0K0γ has been obtained
