Abstract

I review the status of lattice simulations relevant for phenomenological studies of B-physics. Results for much-studied quantities such as f_B, B_B and form-factors for semileptonic decays are presented as well as those for quantities which have begun to be studied only recently (such as B-lifetimes). The improvement in the precision of the determinations of the mass of the b-quark, which has been made possible by new results for perturbative coefficients, is discussed. Finally I describe new ideas being developed with the aim of making computations of two-body non-leptonic decays possible.
