| Sumario: | I present a brief introduction to the lattice formulation of quantum field theory, and discuss the use of lattice simulations for studies in particle physics phenomenology. The computation of f_B, the decay constant of the B-meson, is used as a case study. I also explain the appearance and cancellation of ``renormalons'' in the evaluation of power corrections (higher-twist corrections) in hard scattering and decay processes. |
