It has long been expected that the spectrum of hadrons in QCD would be far
richer and extensive than experiment has so far revealed. While there have been
experimental hints of this richness for some time, it is really only in the
last few years that dramatic progress has been seen in the exploration both
experimentally and in calculations on the lattice. Precision studies enabled by
new technology both with detectors and high performance computations are
converging on an understanding of the spectrum in strong coupling QCD.
These methodologies are laying the foundation for a decade of potential
discovery that electro and photoproduction experiments at Jefferson Lab, which
when combined with key results on B and charmonium decays from both e+e−
and pp colliders, should turn mere impressions of the light meson spectrum
into a high definition picture.Comment: 9 pages, 7 figure
