Measuring the finite width and unitarity corrections to the phi-omega mixing amplitude

N. N. Achasov, A. A. Kozhevnikov

It is shown that the phase of phi-omega interference in the reaction e^+e^- -->pi^+ pi^- pi^0 at energies close to the phi(1020) peak can be calculated in a way that is practically…

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…

Interference in the reaction $e^{+} e^{-} \to γ π^{+} π^{-}$ and the final state interaction

N. N. Achasov, V. V. Gubin

We describe the interference between amplitudes $e^{+} e^{-} \to ρ \to γ π^{+} π^{-}$ and $e^{+} e^{-} \to ϕ \to γ (f_{0} + σ) \to γ π^{+} π^{-}$ , with regard to the phase of the elastic $π π$ scattering backg…

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…
