Tensor glueball-meson mixing phenomenology

The overpopulated isoscalar tensor states are sifted using Schwinger-type m ass relations. TWO solutions are found: one Where the glueball is the f(J)( 2220), and one where the glueball is more distributed, with f(2)(1820) havi ng the largest component. The f(2)(1565) and f(J)(1710) cannot be accommoda ted as glueball-(hybrid) meson mixtures in the absense of significant coupl ing to decay channels. f(2)'(1525) --> pi pi is in agreement with experimen t. The f(J)(2220) decays neither flavour democratically nor is narrow.
