We have measured the branching ratio BR(φ->π 0 π 0 γ) with the KLOE detector using a sample of ~5x10 7 φ decays. φ mesons are produced at DAΦNE, the Frascati φ-factory. We find BR(φ->π 0 π 0 γ)=(1.09+/-0.03 stat +/-0.05 syst )x10 -4 . We fit the two-pion mass spectrum to models to disentangle contributions...
In a sample of 5.3x10 7 , φ-decays observed with the KLOE detector at the Frascati φ-factory DAΦNE we find 605 ηπ 0 γ events with η->γγ and 197 ηπ 0 γ events with η->π + π - π 0 . The decay ηπ 0 γ is dominated by the process φ->a 0 γ. From a fit to the ηπ 0 mass spectrum we find BR(φ->a 0 (980)γ)=(7.4+/-0.7)x10...
