We have measured the branching ratio BR(phi-->pi(0)pi(0)gamma) with the KLOE detector using a sample of similar to5x10(7) phi decays. phi mesons are produced at DAPhiNE, the Frascati phi-factory. We find BR(phi-->pi(0)pi(0)gamma) = (1.09+/-0.03(stat)+/-0.05(syst)) x 10(-4). We fit the two-pion mass spectrum to models to disentangle contributions from various sources.

Abstract
We have measured the branching ratio BR(phi-->pi(0)pi(0)gamma) with the KLOE detector using a sample of similar to5x10(7) phi decays. phi mesons are produced at DAPhiNE, the Frascati phi-factory. We find BR(phi-->pi(0)pi(0)gamma) = (1.09+/-0.03(stat)+/-0.05(syst)) x 10(-4). We fit the two-pion mass spectrum to models to disentangle contributions from various sources.File in questo prodotto:
