Query: QCD Down Under: Building Bridges   The strong coupling regime of QCD is responsible for 99% of hadronic
phenomena. Though considerable progress has been made in solving QCD in this
non-perturbative region, we nevertheless have to rely on a disparate range of
models and approximations. If we are to gain an understanding of the underlying
physics and not just have numerical answers from computing `` black'' boxes, we
must build bridges between the parameter space where models and approximations
are valid to the regime describing experiment, and between the different
modellings of strong dynamics. We describe here how the
Schwinger-Dyson/Bethe-Salpeter approach provides just such a bridge, linking
physics, the lattice and experiment.
