Lattice Gauge Theory

Abstract

The status of lattice calculations in Quantum Field Theory is reviewed. A major part is devoted to recent progress in formulating exact chiral symmetry on the lattice. Another topic which has received a lot of attention is the influence of dynamical quark effects. Attempts to quantify these effects for the light hadron spectrum and flavour singlet amplitudes are discussed, as well as other expected qualitative features of simulations with dynamical quarks. The remaining parts of the review include recent results for the light quark masses using non-perturbative renormalisation and the spectrum of glueballs and heavy hybrids computed using anisotropic lattices.
