Abstract
A sample of 5.3 × 107φ mesons, produced at the Frascati φ-factory DAΦNE, has been used by the KLOE Collaboration to study the φ radiative decays. The decays φ → ηπ0γ and φ → π0π0γ have been exploited to study the scalar mesons a0(980) and f0(980). Furthermore a new determination of the η − η mixing angle has been obtained from the measurement of the ratio of the decay rates of φ → η γ to φ → ηγ.File allegati a questo prodotto
