Filtering overpopulated isoscalar tensor states with mass relations - art.no. 014011

Schwinger-type mass formulas are used to analyze glueball-meson mixing for isoscalar tensor mesons. In one solution, the f(J)(2220) is the physical gl ueball, and in the other the glueball is distributed over various states, w ith f(2)( 1810) having the largest glueball component. Neither the f(2)(156 5) nor the f(J)(1710) are among the physical states without assuming signif icant coupling to decay channels. The decay f(2)(1525)-->pi pi is consisten t with experiment, and f(J)(2220) is neither narrow nor decays flavor democ ratically.
