چکیده
We use QCD sum-rules to study the decays φ → ηγ and φ → η′γ, obtaining B(φ → ηγ) = (1.15±0.2) 10−2 and B(φ → η′γ) = (1.18±0.4) 10−4, in very good agreement with existing experimental data. We also discuss the issue of η−η′ mixing, predicting the η and η′ decay constants in a mixing scheme in the quark-flavour basis.

0 v 1 5 J un 2 00 2 Measurement of Γ ( φ → η ′ γ ) / Γ ( φ → ηγ ) and the pseudoscalar mixing angle
We have measured the radiative decays φ → ηγ , φ → ηγ selecting π+ π γ γ γ final state in a sample of ∼5×107 φ-mesons produced at the Frascati φ–factory DAΦNE. We obtain Γ(φ → ηγ )/Γ(φ → ηγ ) = (4.70 ± 0.47 ± 0.31) × 10−3. From this result we derive new accurate values for the branching ratio BR(φ → ηγ ) = (6.10 ± 0.61 ± 0.43) × 10−5 and the mixing angle of pseudoscalar mesons in the flavour ba...
متن کاملRadiative φ-meson decays and η-η′ mixing: a QCD sum rule analysis
The radiative transitions φ → ηγ and φ → η′γ are analysed using QCD sum-rules. At leading order in perturbative QCD, we obtain the results: B(φ → ηγ) = (1.15 ± 0.2) 10−2 and B(φ → η′γ) = (1.18 ± 0.4) 10−4, in very good agreement with existing experimental data. The related issue of η-η′ mixing is discussed and we give predictions for the η and η′ decay constants in the framework of a mixing sch...
متن کاملKLOE first results on hadronic physics
The KLOE detector (1) at DAΦNE, the Frascati φ-factory, has started taking data in April 1999 and a total integrated luminosity of 2.4 pb has been collected by the end of ’99, corresponding to ∼8 millions φ decays. With these data a preliminary measurement of φ radiative decays φ → ηγ, φ → πγ, φ → ηγ, φ → ππγ, φ → ππγ, φ → ηπγ and of the hadronic decay φ → πππ has been performed. The energy spe...
متن کاملA global fit to determine the pseudoscalar mixing angle and the gluonium content of the η ’ meson
We update the values of the η-η mixing angle and of the η gluonium content by fitting our measurement Rφ = BR(φ → ηγ)/BR(φ → ηγ) together with several vector meson radiative decays to pseudoscalars (V → Pγ), pseudoscalar mesons radiative decays to vectors (P → V γ) and the η → γγ, π0 → γγ widths. From the fit we extract a gluonium fraction of Z2 G = 0.12±0.04, the pseudoscalar mixing angle ψP =...
متن کاملLight Meson Spectroscopy with the Kloe Experiment
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 ...
