Simulations that use the clover action in quenched
QCD calculations have a lower limit to the quark mass that can be
reached, because of the fluctuations caused by exceptional
configurations. From thi...

We present results from a simulation of quenched
overlap fermions with L\"uscher-Weisz gauge field action on
lattices up to $24^3 48$ and for pion masses down to $\approx 250$
MeV. Among the quantitie...
We explore the transitions B$(0^+)$ to B $\pi$ and
B$_s(0^+)$ to B K from lattice QCD with $N_f=2$ flavours of sea
quark, using the static approximation for the heavy quark. We
evaluate the effective ...
We explore the decay of a vector meson to two
pseudoscalar mesons on the lattice with $N_f=2$ flavours of sea
quark. Although we are working with quark masses that do not allow
a physical decay, we sh...
Hadronic decays and transitions are a key
ingredient of hadronic physics. I discuss how hadronic decays can
be explored in lattice gauge theory and review studies undertaken.
I also discuss the impact...
I review the lattice QCD approach to determining
hadronic decay transitions. Examples considered include rho to pi
pi; b_1 to pi omega; hybrid meson decays and scalar meson decays. I
discuss what latt...
We discuss strategies to determine hadronic decay
couplings from lattice studies. As an application, we explore the
decay of a vector meson to two pseudoscalar mesons with N-f = 2
flavours of sea quar...
Lattice QCD determinations appropriate to hadron
spectroscopy are reviewed with emphasis on the glueball and hybrid
meson states in the quenched approximation. Hybrids are discussed
for heavy and for ...
I discuss strategies to determine hadronic decay
couplings from lattice studies. As a check of the methods, I
explore the decay of a vector meson to two pseudoscalar mesons with
N-f = 2 flavours of se...
