Bertsch Dept. of Physics and Institute for Nuclear Theory, FM-15 University of Washington Seattle, WA 98195 Abstract The interferometric analysis of meson correlations provides a measure of the average phase space density of the mesons in the final state. This quantity is a useful indicator of ...

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...
