Finite width effects in φ radiative decays
The decay widths φ → γf0(980) and φ → γa0(980) are calculated taking into account the finite widths of the scalar resonances f0(980) and a0(980). The latter are shown to be essential in order to obtain meaningful results. Simultaneously we also study the decays φ → γππ and γπη where a good reproduction of the recent experimental data is obtained, pointing out the necessity of a φγKK̄ contact ver...
متن کاملRadiative φ decays.
Radiative φ decays give us an excellent opportunity to study scalar and pseudoscalar mesons below 1 GeV. In this paper, results from different experiments are reviewed and compared.
متن کاملOn Radiative Φ → Ηγ, Φ → Η ′ Γ Decays ∗
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.
متن کاملCharge asymmetry and radiative φ decays ⋆
The study of radiative φ decays into scalar mesons, with subsequent decay into ππγ, constitutes an important topic at the electron-positron collider DAPHNE. The interference of the respective amplitude with the one for ππγ production, where the photon originates from initial state radiation, will allow for unambiguous tests of models for the φ → γf0(→ ππ) amplitude. The forward-backward asymmet...
متن کامل8 Brief report on ‘ Radiative φ decays with derivative interactions ’
We study the line shapes of radiative φ -decays with a direct coupling of the φ meson to the f0(980) and a0(980) scalar mesons. The latter couple via derivative interactions to π0π0 and π0η , respectively. Although the kaon-loop mechanism is usually regarded as the dominant mechanism in radiative φ decays, here we test a different possibility: we set the kaon-loop to zero and we fit the theoret...
