Aspects of Confinement: a Brief Review
A brief and biased overview of the phenomenon of confinement in QCD is
presented in three parts: (1) the definition of confinement, (2) properties of
confinement, (3) ideas of confinement. The second part chiefly consists of a
brief review of recent lattice computations related to confinement while the
third summarizes some of the current analytical approaches to understanding
confinement. These include the Dyson-Schwinger formalism in Landau gauge,
Hamiltonian QCD in Coulomb gauge, and the vortex picture of confinement.Comment: 10 pages, 6 eps figures. Plenary talk at Hadron 2003, Aschaffenburg,

Molecular Interpretation of the X(3872)
The discovery of the X(3872) in the 3\pi J/\psi mode is compelling evidence
for its molecular nature. A successful prediction of this decay mode and other
predictions are reviewed here.Comment: 3 pages, ICHEP proceeding
XYZ States: Theory Overview
Various ideas associated with exotic hadrons, and hadronic structure in
general, are briefly reviewed.Comment: 6 pages, Proceedings of Hadron201
A Canonical Ds(2317)?
It is shown that quark mass dependence induced by one loop corrections to the
Breit-Fermi spin-dependent one gluon exchange potential permit an accurate
determination of heavy-light meson masses. Thus the is a canonical
meson in this scenario. The multiplet splitting relationship of
chiral doublet models, , holds to good accuracy
in the and systems, but is accidental. Radiative transitions and
bottom flavoured meson masses are discussed.Comment: 7 pages, 6 figures. References improve
