摘要:

我们研究了$f_0(1710)$标量介子衰变为单光子和单矢量介子($ρ$,$ω$和$ϕ$)中介子环的相关性.特别地,我们估计了来自$f_0(1710)$衰变为两个赝标介子的环的大小,在环中包含三个赝标介子或两个赝标和一个矢量介子。结果,尽管有很大的不确定性,表明介子环的贡献,这些辐射衰变是相当相关的,应该考虑到的理论计算,使用这个可观的测试可能胶球性质的这种共振。

英文摘要:

We investigate the relevance of the meson loops in the $f_0(1710)$ scalar meson decay into one photon and one vector meson, ($ρ$, $ω$ and $ϕ$). In particular we estimate the size of the loops coming from the decay of the $f_0(1710)$ into two pseudoscalar mesons, containing three pseudoscalar mesons in the loop or two pseudoscalar and one vector meson. The results, despite having large uncertainties, manifest that the contribution of the meson loops to these radiative decays is quite relevant and should be taken into account by the theoretical calculations which use this observables as a test of the possible glueball nature of this resonance.
