We analyze the systematic errors made when using the generalized eigenvalue problem to extract energies and matrix elements in lattice gauge theory. Effective theories such as HQET are also discussed. Numerical results are shown for the extraction of ground-state and excited B-meson masses and the ground-state decay constant in the static approximation.

We investigate energy (momentum) distributions in J/ψ photoproduction and J/ψ production in B meson decay. In particular the upper endpoint region of the spectrum is examined where the effect of soft gluon emission from the cc̄ pair becomes important. Constructing a model which is consistent with the so-called shape function formalism we consider these fragmentation effects and show that the rel...

These are notes of lectures given at The NATO Advanced Study Institute/EC Summer School on " New Theoretical Approaches to Strongly Correlated Systems " , (Newton Institute, April 2000). They are a sequel to the notes I wrote two years ago for the Summer School, " Topological Aspects of Low Dimensional Systems " , (Les Houches, July 1998). In this second part, I review the form-factors techniqu...
