Within the framework of a nonlinear chiral Lagrangian the mass spectra and the decay properties of 0^++ states below 2 GeV are studied. Assuming that f0(980), a0(980), K0(1430), and f0(1500) comprise an SU(...

Using Tadpole-improved lattice action,the low-lying glueball spectrum of the pure-gauge SU(2)theory is calculated on an anisotropic lattice.The results of m(0+),m(2+),and m(0-)are consistent with that for the Wilson a...
