Search for $a_{0} (980)$ and $f_{0} (980)$ mesons in $ϕ \to γ K K ˉ$

N. N. Achasov, V. V. Gubin

We study the decay $ϕ \to γ K^{+} K^{-}$ taking into account the scalar mesons production $ϕ \to γ (f_{0} + a_{0}) \to γ K^{+} K^{-}$ and the final state radiation. We note that the relative sign between…

Comment on "Radiative decays, nonet symmetry and SU(3) breaking" by M. Benayoun et al

N. N. Achasov, V. V. Gubin

We comment on the paper by Benayoun, DelBuono, Eidelman, Ivanchenko, and O'Connell [Phys. Rev. {\bf D 59}, 114027 (1999)]. We show that the decay $ϕ \to π^{0} γ$ is absent in model of t…

Analysis of preliminary data on $e^{+} e^{-} \to ϕ \to γ f_{0} (980) \to γ π^{0} π^{0}$ reaction

N. N. Achasov, V. V. Gubin

We perform the analysis of the preliminary data on $e^{+} e^{-} \to ϕ \to γ f_{0} (980) \to γ π^{0} π^{0}$ reaction simultaneously with the data on $π π$ scattering and reactions $J / ψ \to ϕ π^{+} π^{-}$ and $K^…

Search for the scalar a_0 and f_0 mesons in the ϕradiative decays

N. N. Achasov, V. V. Gubin

The potentialities of the production of the $a_{0}$ and $f_{0}$ mesons in the $ϕ$ radiative decays are considered based on a new two-channel analysis of the $π π$ scattering in a energy…

The interference in the reaction $e^{+} e^{-} \to γ π^{+} π^{-}$ and the search for the decay $ϕ \to γ f_{0} \to γ π^{+} π^{-}$

N. N. Achasov, V. V. Gubin, E. P. Solodov

We describe the interference between amplitudes $e^{+} e^{-} \to ρ \to γ π^{+} π^{-}$ and $e^{+} e^{-} \to ϕ \to γ f_{0} \to γ π^{+} π^{-}$ , where $f_{0}$ meson is considered in the frameworks of the four-quar…

Production of scalar $K K ˉ$ molecules in $ϕ$ radiative decays

N. N. Achasov, V. V. Gubin, V. I. Shevchenko

The potentialities of the production of the scalar $K K ˉ$ molecules in the $ϕ$ radiative decays are considered beyond the narrow resonance width approximation. It is shown that…
