*Bottom Hadron Spectroscopy From Lattice QCD*

Stefan Meinel
College of William and Mary

Lattice studies of hadrons containing b quarks are important for several
reasons. In addition to the calculation of matrix elements needed for
flavor physics, lattice QCD can predict masses of b hadrons and solve
puzzles in spectroscopy such as those concerning the recently discovered
Omega_b and eta_b. Including b quarks in lattice QCD calculations requires
special techniques because the lattice spacing presently cannot be chosen
fine enough to resolve their Compton wavelength. In this talk I will give
an introduction to lattice methods for heavy quarks, focusing on
nonrelativistic QCD. I will then present recent results for the
spectroscopy of heavy hadrons, including precise calculations of the
bottomonium spectrum and the mass of the triply-bottom baryon Omega_bbb.
