Study of the decay φ → π + π − π 0 with the KLOE detector

چکیده
We present a study of the reaction e+e−→π+π−π0 at the φ peak, W = M(φ) =1019.4 MeV, observed with the KLOE detector at DAΦNE. The reaction is dominated by φ production and decay, e+e−→φ→π+π−π0. From a fit to the Dalitz plot density distribution we obtain the ρ-meson parameters for its three charge states. We also find the relative amplitudes for φ→ρπ and φ→π+π−π0 and the cross section for e+e− → ωπ0 with ω → π+π−.

متن کاملMeasurement of the absolute branching ratio of the K + → π + π 0 ( γ ) decay with the KLOE detector The KLOE Collaboration
We have measured the absolute branching ratio of the K+ → π+π0 (γ) decay, using ∼20 million tagged K+ mesons collected with the KLOE detector at DAΦNE, the Frascati φ–factory. Signal counts are obtained from the fit of the distribution of the momentum of the charged decay particle in the kaon rest frame. The result, inclusive of final-state radiation, is BR(K+ → π+π0 (γ))=0.2065± 0.0005stat ± 0...
متن کاملStudy of the Decay φ → π 0 π 0 γ with the KLOE Detector The KLOE Collaboration
We have measured the branching ratio BR(φ → ππγ) with the KLOE detector using a sample of ∼5 × 10 φ decays. φ mesons are produced at DAΦNE, the Frascati φ-factory. We find BR(φ→ππγ)= (1.09 ± 0.03stat ± 0.05syst)× 10 . We fit the two–pion mass spectrum to models to disentangle contributions from various sources.

In this paper we describe the status of the analyses in progress on light meson spectroscopy in the KLOE experiment. We present the analyses of φ decays into f 0 (980)γ and a 0 (980)γ, the Dalitz plot analysis of the η → π + π − π 0 decay, the branching ratio measurement of η → π 0 γγ, the upper limits on Br(η → 3γ) and Br(η → π + π −), the measurement of the ratio Br(φ → η ′ γ)/Br(φ → ηγ) and ...
