LATTICE QCD AND THE STANDARD MODEL

Most of the poorly known parameters of the Standard Model cannot be de termined without reliable calculations in nonperturbative QCD. Lattice gauge theory provides a first-principles definition of the required f unctional integrals, and hence offers ways of performing these calcula tions. This paper reviews the progress in computing hadron spectra and electroweak matrix elements needed to determine alpha(S), the quark m asses, and the Cabibbo-Kobayashi-Maskawa matrix.
