Abstract

After a pedagogical introduction to the calculation of weak matrix elements on the lattice, I review some of the lattice's most recent predictions concerning the weak decays of B-mesons. Amongst the topics covered are the determinations of the leptonic decay constant f(B), of the form factors relevant for semi-leptonic B --> D(D-)l<(nu)over bar> decays and of the hadronic matrix element which describes the rare decay B --> K()gamma. Emphasis is placed on the results of the UKQCD Collaboration. Corrections to the heavy-quark limit are discussed extensively.
