A New Approach to the Problem of Dynamical Quarks in Numerical Simulations of Lattice QCD
Martin Luescher
Abstract
Lattice QCD with an even number of degenerate quark flavours is shown to be a limit of a local bosonic field theory. The action of the bosonic theory is real and bounded from below so that standard simulation algorithms can be expected to apply. The feasibility of such calculations is discussed, but no practical tests have yet been made.
