标量胶球:从衰变到$η$或$η'$的约束

Scalar glueballs: Constraints from the decays into $η$ or $η'$

Jean-Marie Frère, Julian Heeck

摘要:

我们研究了标量胶球与等单线态介子$f_0 (1370)$、$f_0(1500)$和$f_0(1710)$的混合,以描述两体衰变到赝标量的过程。我们使用一个有效的哈密顿量,并采用两个角度的混合计划的$η$和$η'$。在这个框架中,我们分析现有的数据,并期待新的数据进入$η$和$η'$渠道。目前,$f_0 (1710)$具有最大的胶球成分和相当大的分支比,可在BESIII测试到$ηη'$。

英文摘要:

We study the mixing of the scalar glueball into the isosinglet mesons $f_0 (1370)$, $f_0(1500)$, and $f_0(1710)$ to describe the two-body decays to pseudoscalars. We use an effective Hamiltonian and employ the two-angle mixing scheme for $η$ and $η'$. In this framework, we analyse existing data and look forward to new data into $η$ and $η'$ channels. For now, the $f_0 (1710)$ has the largest glueball component and a sizable branching ratio into $ηη'$, testable at BESIII.
