The Charm and Beauty of Particle Physics

There are many problems in Quantum Field Theory which cannot be solved
perturbatively. A well known example in particle physics is Quantum
Chromodynamics (QCD-the theory of the strong interactions) at low
energies. Lattice field theory offers a systematic approach to solving
quantum field theories nonperturbatively. In it the space-time continuum
is replaced by a discrete lattice. I will discuss recent advances in
lattice QCD which have let to significant progress in our understanding
of systems invloving heavy (charm and beauty) quarks.
