简介
We have measured the branching ratio BR(φ→π0π0γ) with the KLOE detector using a sample of ∼5×107φ decays. φ mesons are produced at DAΦNE, the Frascati φ-factory. We find BR(φ→π0π0γ)=(1.09±0.03stat±0.05syst)×10−4. We fit the two-pion mass spectrum to models to disentangle contributions from various sources.
