We determine the topological susceptibility in the SU(3) pure gauge theory. We perform a series of high-statistics lattice studies and take the combined continuum and infinite volume limit. We find χtopr 4 0 = 0.0524(7)(6), which translates into χ 1/4 top = 193(1)(8)MeV with the second error exclusively due to the intrinsic scale ambiguity.

In principle, perturbation theory is unnecessary to solve QCD with lattice methods. Even the short distance calculations relating the lattice action to continuum actions could in principle be done by a → 0, V → ∞ brute force Monte Carlo calculations. In practise, perturbation theory has been essential to the progress of lattice methods. It is much easier and more powerful than Monte Carlo for s...

After a brief discussion of the promise and limitations of the lattice technique, I review lattice QCD results for several quantities of phenomenological interest. These are: matrix elements for heavy-to-light meson decays, leptonic decay constants f B and f D , the parameters B B and B K for neutral B and K meson mixing respectively, the strong coupling constant, light quark masses and the lig...
