Abstract
The overpopulated isoscalar tensor states are sifted using Schwinger-type
mass relations. Two solutions are found: one where the glueball is the
fJ(2220), and one where the glueball is more distributed, with
f2(1820) having the largest component. The f2(1565) and fJ(1710)cannot be accommodated as glueball-(hybrid) meson mixtures in the
absense of significant coupling to decay channels.
is in agreement with experiment. The
fJ(2220) decays neither flavour democratically nor is narrow.
