Quarkonium and glueball admixtures of the scalar-isoscalar resonances
$f_{0}(1370), f_{0}(1500)$ and $f_{0}(1710)$    [PDF]

Using the $U(3)_{R}\times U(3)_{L}$ extended Linear Sigma Model with the ordinary (pseudo)scalar and (axial)vector mesons as well as a scalar glueball, we study the vacuum phenomenology of the scalar-isoscalar resonances $f_{0}(1370), f_{0}(1500)$ and $f_{0}(1710)$. We present here a solution, based only on the masses and not yet on decays, in which the resonances $f_{0}(1370)$ and $f_{0}(1500)$ are predominantly nonstrange and strange $\bar{q}q$ states respectively, and the resonance $f_{0}(1710)$ is predominantly a scalar glueball.
