- W4225103673 abstract "Stimulated by the newly observed ${a}_{0}(1817)$ by the BESIII Collaboration, we find a perfect Regge trajectory composed of the ${a}_{0}(980)$, ${a}_{0}(1450)$, and ${a}_{0}(1817)$, which leads us to categorize the ${a}_{0}(980)$, ${a}_{0}(1450)$, and ${a}_{0}(1817)$ into the isovector scalar meson family. This scenario is supported by their two-body Okubo-Zweig-Iizuka allowed strong decay behaviors. In this scheme, we also predict the third radial excitation of the ${a}_{0}(980)$, which is denoted as the ${a}_{0}(2115)$, accessible at future experiment as a direct test of this assignment. We find another Regge trajectory which contains three isoscalar scalar states ${f}_{0}(980)$, $X(1812)$, and ${f}_{0}(2100)$. We investigate their two-body Okubo-Zweig-Iizuka allowed strong decay patterns, which are roughly consistent with the experimental data. The ${f}_{0}(980)$, $X(1812)$, and ${f}_{0}(2100)$ can be well grouped into the isoscalar scalar meson family. We want to emphasize that these two Regge trajectories have a similar slope. In summary, the present work provides a scheme of constructing the scalar meson family based on these reported scalar states. The possibility of the ${f}_{0}(1710)$ as the candidate of the scalar glueball cannot be excluded by the observation of the ${a}_{0}(1817)$ since the ${a}_{0}(1817)$ is more suitable as the isovector partner of the $X(1812)$." @default.
