B -> pi l nu at three lattice spacings
The increasing accuracy of experimental results for the exclusive,
semileptonic decay B -> pi l nu requires a similarly accurate calculation of
the hadronic matrix elements, to determine |Vub|. We present preliminary
results for the form factors of the B to light meson decay mode. Using results
from three lattices in the range 5.7 <= beta <= 6.1 we study the dependence on
the lattice spacing.Comment: LATTICE98(heavyqk), LaTeX, 3 pages, 4 postscript figures, uses

Wave functions and their use in spectroscopy and phenomenology
We describe the calculation of Coulomb gauge wave functions for light quark
systems, and their use as interpolating fields for excited state spectroscopy.Comment: 4 pages latex with lat92 macro plus 4 postscript figs, COLO-HEP-29
Charmed hadron physics in quenched anisotropic lattice QCD
We investigate the anisotropic lattice with improved quark action as a
candidate of framework in which we can treat both the heavy and light quark
region in the same manner and systematically reduce the systematic
uncertainties. To examine applicability of anisotropic lattice, we calculate
the charmed meson spectrum and decay constants in quenched approximation. We
find consistent result with most advanced results on isotropic lattices.Comment: 3 pages, 1 figure, contribution to Fifth KEK Topical Conference -
