Studies of φ meson radiative decays with KLOE

Abstract A sample of 5.3 × 10 7 φ mesons, produced at the Frascati φ-factory DAΦNE, has been used by the KLOE Collaboration to study the φ radiative decays. The decays φ → ηπ 0 γ and φ → π o π o γ have been exploited to study the scalar mesons a o (980) and f o (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 / gf → η ′ γ to φ → ηγ .
