In an earlier work we introduced a covariant model of quarkonium-glueball m
ixing and calculated the wave functions of the various mixed scalar-isoscal
ar states: f(o)(980), f(o)(1370), f(o)(1500), and f(o)(1770). In the presen
t work we introduce the widths of these states and describe glueball mixing
with the f(o)(400-1200) resonance using a perturbative scheme. Part of our
motivation lies in the recent work of Narison who used QCD sum-rule techni
ques to study the distribution of glueball strength among scalar, pseudosca
lar, and tensor mesons. We find little change of our previous results with
little strength in the energy region below the f(o)(980) resonance. Our res
ult is in contrast to the result of the QCD sum-rule analysis that suggests
that there is a good deal of glueball strength in the region near or below
1 GeV.
