We evaluate the continuum limit of the valence (quenched) approximation to the mass of the
lightest scalar quarkonium state, for a range of different quark masses, and to the mixing …

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 …

A general expression resembling the Breit–Wigner formula is derived for the description of
resonances which appear in meson–meson scattering. Our starting point is a unitarised …

Within perturbative QCD approach based on k T factorization, we analyze the scalar mesons
f 0 (980) and f 0 (1500) productions in B decays. By identifying f 0 (980) as the composition …

Resonances appearing in hadronic scattering processes are described by a twophase
model. In the one phase, scattering products are observed, whereas the other phase …

We provide the first explanation of the counter-intuitive scalar glueball couplings to
pseudoscalar mesons found in lattice QCD and predict hitherto uncalculated decay modes …

In these lectures I will show, through three examples, how current lattice calcula-tions are
able to tell us interesting things about the continuum physics of non-Abelian gauge theories …

Lattice QCD determinations appropriate to hadron spectroscopy are reviewed with
emphasis on the glueball and hybrid meson states in the quenched approximation. Hybrids …

Low‐energy meson‐meson scattering data are a powerful testing ground for quark models.
Here, we describe the behaviour at threshold of S‐wave scattering‐matrix singularities. The …
