In the framework of the U(3)R× U(3)L chirally
symmetric extended Linear Sigma Model (eLSM) with three flavors
we investigate the phenomenology
of the three scalar-isoscalar resonances f0(1370), f0(1500), and
f0(1710). The degrees of freedom of the eLSM are (pseudo)scalars
and axial(vectors)
as well as a scalar glueball. In order to understand which of the
scalar-isoscalar states is predominantly a nonstrange, nn=(ūu+dd)/√2, and a strange, ss, quark-antiquark state as
well as predominantly a scalar glueball state we study their mixing
behavior. This is the continuation of the work arXiv:1103.3238 and
aims towards a
full determination of the structure of the scalar-isoscalar mesons
above 1 GeV.
