摘要：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.
