Scalar mesons and the fragmented glueball
The center-of-gravity rule is tested for heavy and light-quark mesons. In the heavy-meson sector, the rule is excellently satisfied. In the light-quark sector, the rule suggests that the a0(980) could be the spin-partner of a2(1320), a1(1260), and b1(1235); f0(500) the spin-partner of f2(1270), f1(1...
