We show that the newly discovered scalar meson f0 (1500) at LEAR has properties
compatible with the lightest scalar glueball predicted by lattice QCD and incompatible with a …

We compute from lattice QCD in the valence (quenched) approximation the partial decay
widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These …

Lattice QCD predictions have motivated several recent studies of the mixing between the
predicted J^PC=0^++ glueball and a q̄q nonet in the 1.3→1.7 GeV region. We show that …

We discuss theoretical predictions for the existence of exotic (non-quark-model) mesons and
review prominent experimental candidates. These are especially the f0 (1500) and f0 (1710) …

Since glueballs are SU (3) Flavor singlets, they should couple equally to u, d, and s quarks,
so that equal coupling strengths to π+ π-and K+ K-are expected. However, we show that …

Computations in the quenched approximation on the lattice predict the lightest glueball to be
a scalar in the 1.5–1.8 GeV region. Here we calculate the dynamical effect the coupling to …

The isosinglet scalar mesons f 0 (1710), f 0 (1500), f 0 (1370) and their mixing are studied.
We employ two recent lattice results as the starting point; one is the isovector scalar meson a …

For the first time a complete data set of the two-body decays of the f0 (1370), f0 (1500) and f0
(1710) into all pseudoscalar mesons is available. The implications of these data for the …

We study the a0 and sigma mesons with the overlap fermion in the chiral regime with the
pion mass as low as 182 MeV in the quenched approximation. After the eta'pi ghost states …
