Estimates of Absolute Branching Fractions for the f0(1710) Decays and Radiative Transitions ψ(2S) → γf0(1710) and ϒ(1S) → γf0(1710)

Аннотация

Using the result of the VES Collaboration for Br(J/ψ→γf0(1710))">$Br(J\text{/}\psi \to \gamma f_0(1710))$, we estimate the absolute branching fractions for the f0(1710)">$f_0(1710)$ decays into ππ">$\pi \pi$, KK¯">$K\overline{K}$, ηη">$\eta \eta$ and for the first time into ωω">$\omega \omega$ and ωϕ">$\omega \varphi$. In addition, we estimate for the first time Br(ψ(2S)→γf0(1710))">$Br(\psi (2S)\to \gamma f_0(1710))$ ≈ 3.5 × 10^–5 and Br(Υ(1S)→γf0(1710))">$Br(\mathrm{{\rm Y}}(1S)\to \gamma f_0(1710))$ ≈ 1 × 10^–5
